[0002] UAV is the abbreviation of unmanned aircraft. It uses radio remote control equipment and self-contained program control devices to achieve unmanned flight. UAVs are generally equipped with batteries to provide power. UAV battery charging cabinets are devices that provide automatic charging and storage functions for UAVs. They can fully charge UAVs in a short time and improve the operating efficiency of UAVs.

[0003] When the drone battery is charged through the charging cabinet, the disassembled drone battery needs to be plugged into the charging compartment of the charging base for charging. On the one hand, since the opening size of the charging compartment is close to the battery size, and the charging base with the charging compartment is located inside the charging cabinet with limited space, it is impossible to ensure that the battery follows the predetermined path and direction during the battery insertion process, which will increase the risk of battery damage and charging compartment damage caused by misoperation or improper insertion. On the other hand, after the battery is inserted, there will be a gap between the battery and the inner wall of the charging compartment. When the charging cabinet shakes due to external factors, it will cause the battery to shake. The shaking battery will cause poor contact between the charging interface and the charging base, resulting in reduced charging efficiency. Utility Model Content

[0004] The purpose of the utility model is to propose a drone battery charging cabinet to solve the problem that the existing charging cabinet cannot stably insert the battery when charging the drone battery, which may easily cause battery damage, and the battery is not stable after insertion, resulting in poor contact between the charging interface and the charging seat.

[0005] In order to achieve the above purpose, the utility model adopts the following technologies:

[0006] A drone battery charging cabinet comprises a cabinet body, a cabinet door is hingedly connected to the front side of the cabinet body, a charging seat is arranged inside the cabinet body through a support plate, a charging compartment is opened on the charging seat, a limit guide component is arranged at the top of the charging seat around the opening of the charging compartment, and an expansion monitoring component is arranged on the inner wall of the charging compartment;

[0007] The drone battery is inserted into the charging compartment through a limiting guide component, and the expansion of the drone battery inserted into the charging compartment is monitored through an expansion monitoring component.

[0008] As a further description of the above technical solution: the limiting guide assembly includes a guide roller arranged above the opening of the charging compartment through a mounting plate, a connecting hole is provided at the top of the mounting plate, and connecting shafts matching the connecting hole are provided at both ends of the guide roller, and a buffer sleeve is provided on the outside of the guide roller.

[0009] As a further description of the above technical solution: a cavity is formed inside the buffer sleeve, and micropores communicating with the cavity are formed on the outer surface of the buffer sleeve.

[0010] As a further description of the above technical solution: a storage channel is opened on the guide roller near its end, one end of the connecting shaft passes through the end of the guide roller and extends into the storage channel, and one end of the connecting shaft located in the storage channel is provided with a sliding seat matching the storage channel, and a spring is provided between the sliding seat and the inner wall of the storage channel.

[0011] As a further description of the above technical solution: a limit strip is arranged on the slide seat, and a limit groove matching with the limit strip is opened on the inner wall of the storage channel.

[0012] As a further description of the above technical solution: the expansion monitoring component includes a thin film pressure sensor fixed to the inner wall of the charging compartment by adhesive bonding, a flexible circuit sheet is fixedly connected to the thin film pressure sensor, and a plug connector is provided at one end of the flexible circuit sheet.

[0013] As a further description of the above technical solution: the number of the thin film pressure sensors is four and they are respectively arranged on the four inner walls of the charging compartment.

[0014] As a further description of the above technical solution: slide rails are arranged on both sides of the support plate, and a handle is arranged at the front end of the support plate, and a slide groove matching with the slide rails is opened on the inner wall of the cabinet.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0016] 1. By setting a limit guide assembly above the charging compartment opening of the charging seat, when the battery is inserted into the charging compartment for charging, the guide roller can guide the battery to ensure that the battery is inserted into the charging compartment in a predetermined path and direction, thereby reducing the risk of battery damage or damage to the charging compartment due to misoperation or improper insertion. When the battery is inserted into the charging compartment for charging, the guide roller is pressed against the outside of the battery through the buffer sleeve. The guide roller and the buffer sleeve can improve the stability of the battery and prevent the battery from shaking due to the shaking of the charging cabinet.

[0017] 2. By setting an expansion monitoring component on the inner wall of the charging compartment, a thin film pressure sensor is set in the charging compartment with adhesive. After the battery is inserted, the thin film pressure sensor is attached to the surface of the battery.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 8 The present embodiment provides a drone battery charging cabinet, comprising a cabinet body 1, a cabinet door 2 being hingedly connected to the front side of the cabinet body 1, a charging seat 4 being arranged inside the cabinet body 1 through a support plate 3, a charging compartment 5 being provided on the charging seat 4, a limiting guide component 6 being arranged at the top of the charging seat 4 around the opening of the charging compartment 5, an expansion monitoring component 7 being arranged on the inner wall of the charging compartment 5, the drone battery being inserted into the charging compartment 5 through the limiting guide component 6, and the expansion of the drone battery inserted into the charging compartment 5 being monitored through the expansion monitoring component 7.

[0032] In the utility model, when charging the drone battery, the cabinet door 2 of the cabinet body 1 is opened, and then the drone battery is inserted into the charging compartment 5 of the charging seat 4. When the battery is inserted, the bottom of the drone battery will first contact the limit guide component 6, and then the drone battery is accurately inserted into the charging compartment 5 under the guidance of the limit guide component 6, so as to avoid the drone battery from colliding with the charging compartment 5 during charging and causing damage to the battery. After the drone battery is inserted into the charging compartment 5, it is connected to the charging connector in the charging compartment 5 and charged. At this time, the limit guide component 6 is against the outside of the drone battery, so as to fix the drone battery, and avoid shaking and collision between the battery and the charging compartment 5 due to shaking of the charging cabinet during the charging process. The battery expansion is monitored between the battery and the inner wall of the charging compartment 5 through the expansion monitoring component 7. When the battery is overheated and expanded due to improper charging, the expansion monitoring component 7 can detect the battery expansion change in time, so as to deal with the heat-expanded battery in time.

[0033] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the limiting guide assembly 6 includes a guide roller 63 arranged above the opening of the charging compartment 5 through a mounting plate 61, a connecting hole 62 is provided at the top of the mounting plate 61, and connecting shafts 64 matching the connecting hole 62 are provided at both ends of the guide roller 63, and a buffer sleeve 65 is provided on the outside of the guide roller 63.

[0034] Among them, the guide roller 63 is rotatably installed between the mounting plate 61 through the connecting shaft 64 and the connecting hole 62, and four guide rollers 63 are installed at the opening position of the charging compartment 5 of the charging seat 4 using the mounting plate 61. The four guide rollers 63 are respectively against the four sides of the drone battery when the drone battery is charged. The rotating guide rollers 63 can be used to guide the battery during charging. The battery contacts the guide rollers 63 first when inserted into the charging compartment 5. As the battery is continuously pressed down, the rotating guide rollers 63 guide the battery, so that the battery can be accurately inserted into the charging compartment 5, and avoid the battery and the charging compartment 5 from colliding during the insertion process. The buffer sleeve 65 outside the guide roller 63 can play a buffering role. When the battery is inserted into the charging compartment 5 for charging, the buffer sleeve 65 is against the outside of the battery, thereby preventing the battery from shaking on the charging compartment 5 when the charging cabinet shakes due to external interference, thereby improving the stability of the battery and preventing poor contact between the charging interface and the charging seat 4.

[0035] Specifically, Figure 5 As shown, a cavity 651 is formed inside the buffer sleeve 65, and a micropore 652 is formed on the outer surface of the buffer sleeve 65 and is connected to the cavity 651. When the battery is charged in the charging compartment 5 and shakes, the battery will first squeeze the buffer sleeve 65, which is made of rubber. When the battery squeezes the buffer sleeve 65, the air in the cavity 651 is compressed, thereby absorbing part of the energy generated by the collision to achieve a better buffering effect. The micropore 652 is connected to the cavity 651, which can allow air to flow when the buffer sleeve 65 is hit, which helps to restore the original shape of the buffer sleeve 65 more quickly after the collision.

[0036] Specifically, Figure 4 and Figure 6 As shown, a receiving channel 631 is provided on the guide roller 63 near its end, one end of the connecting shaft 64 passes through the end of the guide roller 63 and extends into the receiving channel 631, and one end of the connecting shaft 64 located in the receiving channel 631 is provided with a slide seat 641 that cooperates with the receiving channel 631, and a spring 633 is provided between the slide seat 641 and the inner wall of the receiving channel 631.

[0037] Among them, the spring 633 squeezes the slide 641 to fix the connecting shaft 64 on the slide 641 to the end of the guide roller 63. When the guide roller 63 is damaged and needs to be repaired and replaced, the connecting shaft 64 in the connecting hole 62 of the mounting plate 61 is squeezed toward the middle position of the guide roller 63. The connecting shaft 64 is subjected to force and squeezes the spring 633 through the slide 641. The spring 633 contracts to shrink the connecting shaft 64 in the storage channel 631, so that the connecting shaft 64 is separated from the connecting hole 62 of the mounting plate 61. At this time, the guide roller 63 can be pulled out from between the two mounting plates 61 to realize the disassembly of the guide roller 63. Similarly, when installing the guide roller 63, the connecting shaft 64 is first squeezed into the storage channel 631. As the connecting shaft 64 is aligned with the connecting hole 62, the connecting shaft 64 pops out and is inserted into the connecting hole 62 under the action of the spring 633, thereby realizing the installation of the guide roller 63 between the mounting plates 61.

[0038] It should be noted that a limit strip 642 is provided on the slide 641, and a limit groove 632 matching the limit strip 642 is provided on the inner wall of the receiving channel 631. The limit strip 642 and the limit groove 632 can limit the slide 641 and the connecting shaft 64 in the circumferential direction, thereby preventing the connecting shaft 64 and the guide roller 63 from rotating relative to each other, thereby reducing the wear between the connecting shaft 64 and the guide roller 63.

[0039] Specifically, Figure 3 and Figure 7 As shown, the expansion monitoring component 7 includes a thin film pressure sensor 71 which is fixed to the inner wall of the charging compartment 5 by means of an adhesive backing 72, a flexible circuit sheet 73 is fixedly connected to the thin film pressure sensor 71, and a plug connector 74 is provided at one end of the flexible circuit sheet 73. There are four thin film pressure sensors 71 which are respectively arranged on the four inner walls of the charging compartment 5.

[0040] The thin film pressure sensor 71 is fixed by the adhesive 72. When the battery is inserted into the charging compartment 5 for charging, the thin film pressure sensor 71 is attached to the outside of the battery. When the battery is overheated and expands due to improper charging, the expanded battery will squeeze the thin film pressure sensor 71, thereby increasing the pressure on the thin film pressure sensor 71. The thin film pressure sensor 71 transmits the pressure signal through the flexible circuit sheet 73, so that the battery abnormality can be detected in time when the battery is overheated.

[0041] It should be noted that the thin film pressure sensor 71 adopts a resistive sensor of model RP-S40-ST, and its pressure sensing range is 10g-20kg, which can meet the pressure detection needs when the battery expands.

[0042] Specifically, Figure 1 and Figure 8As shown, slide rails 31 are provided on both sides of the support plate 3, and a handle 32 is provided at the front end of the support plate 3, and a slide groove 11 matching with the slide rail 31 is provided on the inner wall of the cabinet 1. When the charging seat 4 needs to be inspected and maintained, the handle 32 is used to pull the support plate 3 outward, so that the support plate 3 is moved to the outside of the cabinet 1 through the slide rail 31 and the slide groove 11, so that the charging seat 4 on the support plate 3 can be inspected and maintained.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
