[0054] For details, see the attached Figure 3-4 , the transmission assembly includes two first gear trains, a second gear train and a plurality of racks 7; the two first gear trains are arranged on both sides of the second gear train, the first gear train includes a first rotating shaft 14, the first rotating shaft 14 is installed in two bearing seats 17, and then the first rotating shaft 14 and the inner ring of the bearing are connected by a set screw, and the bearing seat 17 is connected to the warehouse body 2 by bolts and nuts, the first transmission gear 13 is installed on the first rotating shaft 14, and a first bevel gear 16 is also installed in the middle of the first rotating shaft 14. Generally speaking, the first transmission gear 13 and the first bevel gear 16 are installed on the first rotating shaft 14 by keys; the second gear train includes a second rotating shaft 21, and the second rotating shaft 21 is matched with the inner rings of the bearings on both sides by set screws, and second bevel gears 15 are also installed at both ends of the second rotating shaft 21, and the second bevel gears 15 are respectively meshed with the first bevel gears 16 in the two first gear trains, and a second transmission gear 19 is installed in the middle of the second rotating shaft 21, and usually the second rotating shaft 21 is matched with the second bevel gear 15 and the second transmission gear 19 by keys. Furthermore, two racks 7 are vertically provided on the inner side of each warehouse door 6, and threaded holes are provided on the back side of the racks 7. The racks 7 and the warehouse door 6 are connected by bolts, and the position of the racks 7 corresponds to the first transmission gear 13. When the first transmission gear 13 rotates, the first transmission gear 13 engages with the racks 7 accordingly, thereby realizing the opening or closing of the warehouse door 6.

[0055] Of course, in other embodiments, the transmission assembly may not be a gear transmission. Furthermore, the number of racks 7 disposed on the inner side of the door 6 may not be two. The transmission assembly can be configured to open the door 6 through transmission of the transmission assembly when the power unit is started.

[0056] In this embodiment, the power unit includes a motor 23, which is fixed in the second space by a motor bracket 22. A third transmission gear 20 is installed on the rotating shaft of the motor 23, and the third transmission gear 20 is meshed with the second transmission gear 19; wherein the second transmission gear 19 is installed on the second rotating shaft 21.

[0057] For details, see the attached Figure 3-4 In general, the power unit is a motor 23, the motor 23 and the motor bracket 22 are matched with bolts and nuts, the motor bracket 22 is installed in the second space with bolts and nuts, and the third transmission gear 20 is installed on the rotating shaft of the motor 23 with a key. Through this transmission assembly, it is possible to use a power source to drive the left and right doors 6 to move; when the power unit rotates, the third transmission gear 20 is first driven to rotate, and since the second transmission gear 19 is meshed with the third transmission gear 20, the second transmission gear 19 rotates synchronously and drives the second rotating shaft 21 to rotate. When the second rotating shaft 21 rotates, the two second bevel gears 15 rotate with the second rotating shaft 2 1 rotates synchronously. Since the first bevel gear 16 is meshed with the second bevel gear 15, the first bevel gear 16 rotates synchronously and drives the first rotating shaft 14 to rotate. When the two first rotating shafts 14 rotate, the four first transmission gears 13 rotate synchronously. When the first transmission gear 13 rotates, the first transmission gear 13 is meshed with the rack 7 correspondingly, thereby realizing the opening or closing of the warehouse door 6. The warehouse door 6 is connected with a plurality of limit switches 10 at the same time. The limit switches 10 are arranged on the inner side of the side walls at the left and right ends of the warehouse door 6. When the warehouse door 6 moves upward or downward, the contact on the warehouse door 6 will touch the corresponding limit switch 10, thereby interrupting the current movement.

[0058] In this embodiment, the temperature control component includes at least one temperature sensor 5, at least one heat preservation lamp 12 and a control module. The temperature sensor 5 and the heat preservation lamp 12 are both arranged on the inner side of the left wall of the warehouse body 2, and / or the inner side of the right wall, and the temperature sensor 5 and the heat preservation lamp 12 are both located in the first space. The temperature sensor 5 is used to monitor the temperature inside the warehouse body 2 in real time, and the heat preservation lamp 12 is used to provide heat to the inside of the warehouse body 2 when necessary. When the temperature inside the warehouse is too low, the heat preservation lamp 12 is turned on to increase the temperature. The control module is used to receive real-time data from the temperature sensor 5, and provide opening or closing instructions to the heat preservation lamp 12 and the motor 23 when necessary. In this embodiment, the control module is a separate component independent of the drone 1. In other embodiments, the control module can also be a part of the drone 1, as long as the above functions can be achieved.

[0059] The temperature control component also includes at least one motor 11, which is arranged on the outside of the left side wall of the warehouse body 2 and / or the outside of the right side wall. The motor 11 is used to provide power for the blades 4. The blades 4 are arranged on the outside of the side walls at the left and right ends of the warehouse body 2 and at the corresponding positions of the motor 11. When the temperature inside the warehouse body 2 needs to be lowered, the motor 11 drives the blades 4 to rotate. The outer peripheral side of the motor 11 is also provided with a protective cover 3, which is used to prevent the motor 11 from being damaged. It should be noted that the temperature inside the warehouse body 2 can be cooled when the door 6 is opened; when the outside temperature is too high or the temperature of the battery pack 8 is too high, when the door 6 is opened and the cooling effect on the battery pack 8 of the drone 1 is not obvious or cannot meet the needs, the motor 11 is opened to drive the blades 4 to further improve the cooling effect.

[0060] After using the above structure, the drone 1 can increase or decrease the temperature inside the cabin according to the change of the outdoor temperature, so that the battery temperature is within a suitable range.

[0061] Example 2

[0062] In addition, the present invention also provides a method for controlling the constant temperature of a drone battery, which is applied to the device for controlling the constant temperature of a drone battery in 1, and the specific steps are as follows:

[0063] S1. Define the current operating temperature of the battery pack 8 as T, and the suitable operating temperature of the battery pack 8 is a℃<T<b℃;

[0064] S2. When it is detected that T≥b℃, the action mechanism and the temperature control component enter the cooling mode synchronously. At this time, the power unit starts forward, so that the door 6 on the warehouse body 2 opens, and the temperature control component is started to dissipate heat until the temperature in the warehouse reaches a℃<T<b℃, and then the temperature control component is turned off;

[0065] S3. When the temperature sensor 5 detects that T≤a℃, the action mechanism and the temperature control component begin to enter the heating mode. At this time, the power unit starts in reverse, so that the door 6 on the warehouse body 2 is closed, and the temperature control component is started to heat up. When the temperature in the warehouse body 2 is a℃<T<b℃, the temperature control component is closed;

[0066] S4. According to the real-time temperature in the warehouse 2, repeat step S2 or step S3 to form a closed-loop control.

[0067] Specifically, refer to Figure 5For the sake of convenience, it is assumed that the suitable temperature of the battery of the drone 1 is T∈(a,b). When it is used, if the temperature sensor 5 detects that the temperature in the cabin is T≥b℃, it starts to enter the cooling mode: the motor 23 is in the forward direction, and the rack 7 moves downward through the action mechanism. When the contact on the cabin door 6 touches the limit switch 10, the motor 23 stops rotating, the cabin door 6 is in the open state, and the motor 11 drives the blade 4 to rotate and dissipate heat until the temperature sensor 5 detects that the temperature in the cabin is a℃<T<b℃, and the motor 11 stops rotating. If the temperature detected by it rises to T≥b℃ again, the motor 11 is restarted to drive the blade 4 to rotate and dissipate heat. If T≤a℃, it starts to enter the heating mode: the motor 23 reverses, the rack 7 moves upward, and when the contact of the cabin door 6 touches the limit switch, the motor 23 stops rotating, the cabin door 6 is in the closed state, and the heat preservation lamp 12 is turned on to heat the cabin temperature until a℃<T<b℃, and the heat preservation lamp 12 is turned off. In order to extend the heat preservation effect, heat preservation cotton is laid on the cabin door 6 and the cabin body 2. If T≤a°C, turn on the heat preservation lamp 12 for heating again; if T≥b°C, repeat the previous cooling mode, thereby forming a closed-loop controlled battery constant temperature device.
