Detailed Description

The technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to fig. 1 to 12, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

It should be noted that, if the directions related to the embodiment of the present utility model are shown in the drawings, for example, the front and the rear are shown in fig. 1, specifically, the left side of fig. 1 is the front, and the right side of fig. 1 is the rear; meanwhile, as shown in fig. 2, the horizontal direction is approximately the horizontal direction, and the vertical direction is the vertical direction as shown in the figure. If a particular gesture changes, the directional indication changes accordingly.

In the use process of the unmanned aerial vehicle, the unmanned aerial vehicle battery generates larger heat due to longer discharge and use time. In addition, because of the large charging power, the battery needs to be cooled during charging.

Unmanned aerial vehicle battery charging households are as unmanned aerial vehicle battery's battery charging professional equipment, can be fine satisfy and charge management to unmanned aerial vehicle battery. The battery of the unmanned aerial vehicle is inserted into the battery of the unmanned aerial vehicle, and in view of the fact that the size of the existing battery of the unmanned aerial vehicle is large, a part of the battery of the unmanned aerial vehicle is exposed outside the battery of the unmanned aerial vehicle.

As shown in fig. 1 to 3, a battery charging manager for an unmanned aerial vehicle of the present embodiment includes a charging stand 10, a charging control circuit 20, and a cold source generating device 30, wherein the charging stand 10 has at least one charging station 101, the charging control circuit 20 has charging output interfaces with the number identical to that of the charging stations 101, one charging station 101 has one charging output interface 1011, and the cold source generating device 30 is electrically connected with the charging control circuit 20.

The charging stand 10 may be, for example, a box-type structure, and the charging stand 10 has a plurality of charging stations 101 arranged at intervals, for example, three or four. Wherein adjacent charging stations 101 are isolated from each other, specifically, adjacent charging stations 101 are formed with an isolation portion 106 on the upper surface of charging stand 10.

The charge control circuit 20 employs a charge control circuit of an existing charge manager having a controller for controlling the entire charge control circuit. Of course, the controller is also a common controller for existing charge households. Therefore, in the present embodiment, the disclosure of the present utility model cannot be considered insufficient because the composition of the charge/discharge control circuit 20 cannot be fully described.

It should be appreciated that the charge control circuit 20 is provided with a plurality of charge output sockets, a specific number being matched to the charging station 101. I.e. when the number of charging stations 101 is four, the number of charging output sockets is also four. I.e. one said charging output interface is provided at each charging station 101. Of course, the charging output interface described in the present embodiment is an interface for the charging station 101 to charge the unmanned aerial vehicle battery. And may also include other TYPEs of power outlets for the charge control circuit 20, such as a USB output interface, TYPE C interface, etc.

Importantly, each of the charging stations 101 has a plurality of cold source outlets 102; the plurality of cold source output ports 102 are arranged at the non-bottom position of each charging station 101. That is, the cold source output port 102 for heat dissipation is not located at the bottom of the charging station 101 any more, but is located at other positions, so that heat dissipation treatment on other positions can be realized.

Specifically, as shown in fig. 1 and 3, in this embodiment, a cold source output port 102 is provided on a peripheral side of each charging station 101, and a flow passage 103 is provided in the charging stand 10, and the flow passage 103 communicates the cold source output port 102 with an output end of the cold source generating device 30 to output the cold source generating device 30 to the cold source output port 102. In this embodiment, the cold source output port 102 belongs to the external position of the charging stand 10, so as to achieve the heat dissipation treatment on the battery part of the unmanned aerial vehicle exposed outside the charging stand 10.

Specifically, in this embodiment, the cold source generated by the cold source generating device 30 is conveyed to the cold source output port 102 through the flow channel 103 to cool down the battery part located above the cold source output port 102 for performing treatment. Therefore, more comprehensive heat dissipation and temperature reduction treatment of the unmanned aerial vehicle battery is realized. The problem that a traditional charging manager with a cooling and heat dissipation function cannot realize heat dissipation on a battery part exposed above the charging manager is solved.

It should be appreciated that the cold source generating device 30 may be implemented by using a conventional technology, such as a fan or a micro air conditioner. When a fan is used, an inner cavity 108 is disposed in the charging stand 10, the fan is disposed in the inner cavity 108, the inner cavity 108 is communicated with the flow channel 103, a cold source (air flow) generated by the fan enters the flow channel 103 from the inner cavity 108, and the cold source is output to the cold source output port 102 from the flow channel 103, so that the output of the cold source is realized. Specifically, the fan and the micro air conditioner may be implemented by adopting the prior art of a charging manager, which is not described herein, but the technology disclosed in the present utility model should not be considered insufficient.

In some embodiments, in order to better meet the cooling and heat dissipation requirements, a plurality of cold source output ports 102 are uniformly distributed on the periphery of the opening of each charging station 101. Namely, the periphery of each charging station 101 is realized through a plurality of cold source output ports 102, so that the output quantity of the cold sources is ensured, and a better cooling effect is achieved.

In detail, as shown in fig. 4, a plurality of the cold source outlets 102 are arranged around the outline of the charging station 101. I.e. in this embodiment a plurality of said cold source outlets 102 are arranged around said charging station 101. As shown in fig. 4, in some embodiments, the charging station 101 is square, and the plurality of cold source output ports 102 are respectively disposed outside four sides of the square charging station 101. For example, two cold source output ports 102 or three cold source output ports 102 are arranged on the outer side of each side. Of course, the number is not limited to this, and may be set according to a specific actual. Any number of only variable cold source outlets 102 should fall within the protection scheme of the present utility model. In addition, when the charging station 101 is circular, the plurality of cold source output ports 102 are uniformly distributed along the circumferential direction around the circular charging station 101. It should be clear that, in this scheme, the arrangement of cold source delivery outlet 102 is based on the profile setting of charging station 101, is favorable to the cold source that cold source delivery outlet 102 output to blow to unmanned aerial vehicle battery's surface as far as possible like this, and then realizes the heat dissipation.

As shown in fig. 5, each of the cold source outlet 102 is formed of an outlet flow passage 104, and the outlet flow passage 104 is arranged obliquely from bottom to top toward the charging station 101. In this embodiment, since the bottom-up inward inclination is adopted to enable all the cold source output ports 102 to be disposed towards the central axis of the charging station 101, the cold source output along the output flow passage 104 will blow towards the battery along the inclined direction. By the scheme, the cold source can be blown to the battery as much as possible, and therefore optimal heat dissipation performance is guaranteed.

As shown in fig. 6, in some embodiments, the cold source output 102 around each charging station 101 is connected to a separate bypass flow path 105, and the bypass flow path 105 is connected to the flow path 103. That is, the cold source output ports 102 around each charging station 101 can perform uniform cold source output control through the branch flow channels 105, so that the cooling treatment of a single charging station 101 can be satisfied. For example, when three cold source output ports 102 are respectively disposed on the outer side of each side of a square charging station 101, twelve cold source output ports 102 are provided on the periphery of the charging station 101, and the twelve cold source output ports 102 are all connected to one branch flow passage 105, the cold source output by the flow passage 103 enters the branch flow passage 105, and then flows into each output flow passage 104 through the branch flow passage 105, so that the cold source output from the cold source output ports 102 is realized. Wherein the inner diameter of the bypass flow channel 105 is smaller than the inner diameter of the flow channel 103.

Further, as shown in fig. 7, each of the bypass channels 105 is provided with a control valve 40, and the control valve 40 is electrically connected to the charging control circuit 20. The charge control circuit 20 can control the operation of the control valve 40, and can realize the output of a cold source when being opened; and when the cold source is closed, the stop output of the cold source can be realized. The present embodiment achieves the function of a charge manager to perform a single control of each charging station 101. That is, when a certain cooling mode is executed, the charge control circuit 20 may perform cooling on a certain charging station 101 alone. For example, when one charging station 101 of the charging tube having three charging positions 101 performs charging, the charging control circuit 20 may control the cold source generating device 30 to generate a cold source, and open the control valve 40 of the charging station corresponding to the charging, and close the other control valves 40; this allows cooling control of the individual charging stations 101.

It should be appreciated that the control valve 40 in this embodiment is preferably a flow control valve that is capable of controlling the flow of the cold source therethrough. Thus, the control valve 40 can be used for controlling the flow of the cold source when the flow of the cold source is not large. Of course, the control valve 40 may be other types of valves, as long as flow control is enabled. Any type of replacement of only the control valve 40 should fall within the scope of the present utility model.

In some embodiments, the output flow channel 104, the bypass flow channel 105, and the flow channel 103 are tubular structures as shown in fig. 8. I.e. the flow channels are all realized by tubular structures. Such as hoses, copper tubing, steel tubing, etc. These tubular structures are separate components from the cradle 10. The output flow passage 104, the bypass flow passage 105, and the flow passage 103 are collectively referred to as a delivery pipe. The delivery line is of a separate construction from the charging stand 10. That is, the whole delivery line is of an independent structure for delivering the cold source generated by the cold source generating device 30 to the cold source outlet 102. The adoption of such a structural arrangement facilitates the manufacture of the entire charging manager. That is, when the charging stand 10 is set, a corresponding cold source output port 102 is also required to be formed, then a corresponding conveying pipeline is arranged in the charging stand 10, and then two ends of the conveying pipeline are respectively communicated with the corresponding cold source output port 102 and the cold source generating device 30. As shown in fig. 9, the panel 107 of the charging stand 10 is provided with a plurality of cold source output ports 102. Specifically, the panel 107 is provided with the outlet flow passage 104, and the extension 1071 is formed by extending downward from the panel 107. During assembly, the pipe of the conveying pipeline is sleeved with the extension part 1071, so that the conveying pipeline and the cold source output port 102 can be assembled in a communicating way.

Of course, in some other embodiments, the output flow channel 104, the bypass flow channel 105 and the flow channel 103 are formed directly in the charging stand 10, i.e. directly machined at the time of design and molding of the charging stand 10. The specific molding is realized by adopting the prior art, and a detailed description is omitted in this embodiment.

As shown in fig. 10, the cold source outlet 102 is provided with a movable cover plate 50, and the cover plate 50 can shield the cold source outlet 102. Only one cover plate 50 is shown in the figure, and other cold source output ports 102 also have the cover plate, which is not shown in the figure. Specifically, the cover plate 50 is movable, i.e., the cold source outlet 102 can be shielded when needed; when not needed, the cover plate 50 can be removed so that the cold source outlet 102 is exposed for cooling. In this way, it is possible to avoid shielding the cold source output ports 102 when cooling is not required, and prevent foreign substances such as dust from accumulating at these cold source output ports 102. In detail, in some embodiments, the cover 50 and the charging stand 10 may be assembled by fastening, that is, a buckle is provided in the cover 50, and then a fastening hole is provided at the charging stand 10, so that the cover 50 is fastened directly on the charging stand 10 during assembly. Of course, other manners of assembling the cover plate 50 and the charging stand 10 are also possible, such as a sliding manner, so long as the cover plate 50 can shield the cold source outlet 102 when not in use.

In summary, in this embodiment, the cooling source is output to the cooling source output port 102 through the conveying pipeline, so that the battery part outside the charging housekeeper is cooled, and thus the charging efficiency of the charging housekeeper can be improved, and the rotation rate of the battery can be improved.

Additionally, referring to fig. 11, in other embodiments, the bottom of each charging station 101 has a bottom-up protrusion structure 109, and the protrusion structure 109 has a side 1091 exposed inside the charging station 101, and the side 1091 has the cold source output port 102. The cold source output port 102 of the embodiment is arranged on the side surface of the interior, so that the cold source can be output from the side surface to the outside to realize cooling treatment. Specifically, when the cold source generating device 30 radiates heat by a fan, the air flow will flow from the cold source output port 102 to the inner cavity 108 of the charging stand 10, so as to realize cooling. When the cold source generating device 30 is a micro air conditioner, the generated cold source flows from the inner cavity 108 to the cold source output port 102 at the side 1091, and finally enters the charging station 101 to realize cooling treatment from the side.

In detail, the protrusion structure 109 is formed by a bottom-up extending protrusion along one sidewall position of the charging station 101. Of course, the protruding structure 109 is preferably an integral structure with the charging stand 10.

In this embodiment, the cold source output port 102 is in a strip structure, and is specifically disposed along the up-down direction. Each of the side surfaces 1091 has a row of spaced apart strip-shaped cold source outlet openings 102.

As shown in fig. 12, in some embodiments, the bottom of the charging stand 10 has an inner cavity 108, and corresponding mounting posts 110 are disposed in the inner cavity 108, and the number of the mounting posts 110 is preferably four, so as to fix the fan when the cold source generating device 30 is the fan.

The scheme of the embodiment is adopted to realize cooling on the side surface of the inside of the charging station 101, so that the charging and heat dissipation requirements of part of unmanned aerial vehicle batteries are met.

The unmanned aerial vehicle battery can be a battery used in an unmanned aerial vehicle.

Variations and modifications to the above would be obvious to persons skilled in the art to which the utility model pertains from the foregoing description and teachings. Therefore, the utility model is not limited to the specific embodiments disclosed and described above, but some modifications and changes of the utility model should be also included in the scope of the claims of the utility model.
