Description

Technical Field

[0001] This utility model relates to the field of drone battery technology, specifically a drone battery health status assessment device. Background Technology

[0002] Health assessment of drone batteries is crucial for flight safety, performance, and battery life.

[0003] After using a drone for a period of time, the battery status is assessed using a battery health assessment device, which measures the battery's AC or DC internal resistance at a specific frequency. Internal resistance is one of the most critical indicators of battery state of health (SOH), and it increases significantly with aging.

[0004] However, existing drone batteries have a casing on the outside for quick assembly and disassembly with the drone, with the positive and negative terminals of the drone cut out inside the casing. When assessing the health status of the drone, the assessment device needs to connect to the positive and negative terminals of the battery through a test pen. Users can only perform the test by holding different test pens in both hands and touching the positive and negative terminals. Existing assessment devices cannot position the test pens, which is time-consuming, laborious, and reduces work efficiency.

[0005] Furthermore, since the positive and negative terminals of a drone battery are usually located on the inside of the battery, a separate fixing structure is needed to secure the battery before testing can be performed. If it is not secured, the battery will move when the staff touches the positive and negative terminals of the battery with a testing pen, causing the test to fail, which is troublesome and cumbersome. Utility Model Content

[0006] The purpose of this invention is to provide a device for assessing the health status of drone batteries, in order to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a device for assessing the health status of a drone battery, comprising:

[0008] main body;

[0009] A right-angled rod located on the back of the main body is used to support the testing pen located on the positive and negative terminals of the battery;

[0010] The back of the main body is connected to one side of the fixed column via fasteners. One end of the fixed column is connected to one end of the extension column via an embedded connection. The other end of the extension column is connected to one end of the right-angle rod via a sliding connection. The other end of the right-angle rod is connected to the top of the support column via fasteners. The bottom of the support column is connected to the top of the telescopic column via an embedded connection. The bottom of the telescopic column is connected to a buckle via fasteners. The buckle is connected to the detection pen via an engaging connection. A battery is provided on one side of the detection pen, and an angled rod is provided on the side of the battery.

[0011] Preferably, one end of the elastic element is connected to the inside of the support column by a fastener, and the other end of the elastic element is connected to the end of the telescopic column away from the buckle by a fastener. The detection pen is connected to the main body through a circuit.

[0012] Preferably, the back of the main body is connected to one end of the positioning column by fasteners, the outer wall of the positioning column is connected to the rotating column by rotation, and the inner outer wall of the rotating column is connected to the bottom column by a fixing plate.

[0013] Preferably, the rotating column and the bottom column are connected to the bottom of the beveled rod by fasteners in opposite directions, and the top of the beveled rod is connected to the top column by fasteners.

[0014] Preferably, a battery is provided on the bottom post, the battery is located inside the top post, the bottom of the battery is provided with positive and negative terminals, and the detection pen is located at the positive and negative terminals respectively.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] Firstly, this utility model, by setting up a right-angle rod and an extension column, can support the testing pen. After the battery is fixed to the back of the main body, the testing pen is installed on the buckle by a snap-fit ​​mechanism. Pushing the testing pen upward causes it to move the telescopic column inside the support column, compressing the elastic element. The testing pen and the right-angle rod pull the extension column inside the fixed column, causing the extension column to move the testing pen left and right via the right-angle rod. Then, pushing the right-angle rod to slide on the extension column adjusts the front and back position of the testing pen until the bottom of the testing pen is above the positive and negative terminals of the battery. Releasing the testing pen allows the elastic element to push the testing end of the testing pen into the positive and negative terminals of the battery via the telescopic column. The other testing pen is operated in the same way. The main body uses the testing pen to test the internal resistance of the battery, thus achieving the supporting effect for the testing pen of the evaluation device. This eliminates the need for workers to hold two different testing pens in each hand, saving time and effort and effectively improving work efficiency.

[0017] Secondly, this utility model, by setting a bottom column and a top column, can locate the drone battery that needs to be health assessed. Before testing the battery, the end with the positive and negative terminals of the battery is facing downwards, and the bottom of the battery is placed on the bottom column. The battery pushes the bottom column downwards by its own weight, and rotates on the positioning column through the rotating column. The rotation of the rotating column drives the angled plate to rotate, and the angled plate is pressed against the side of the battery through the top column. The bottom column and the top column position the battery, preventing the battery from being placed directly on the table. During the test, the test pen touches the positive and negative terminals, which can easily move the battery, demonstrating the practicality of this device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A device for assessing the health status of a drone battery, comprising:

[0025] Entity 1;

[0026] The right-angle rod 3 located on the back of the main body 1 is used to support the detection pen 10 located on the positive and negative terminals 12 of the battery 11;

[0027] The back of the main body 1 is connected to one side of the fixed column 5 via fasteners. One end of the fixed column 5 is connected to one end of the extension column 6 via an embedded connection. The other end of the extension column 6 is connected to one end of the right-angle rod 3 via a sliding connection. The other end of the right-angle rod 3 is connected to the top of the support column 7 via fasteners. The bottom of the support column 7 is connected to the top of the telescopic column 8 via an embedded connection. The bottom of the telescopic column 8 is connected to the buckle 9 via fasteners. The buckle 9 is connected to the detection pen 10 via a snap-fit ​​connection. A battery 11 is located on one side of the detection pen 10, and an angled rod 4 is located on the side of the battery 11. The detection pen 10 is installed on the buckle 9 via a snap-fit ​​connection. Pushing the detection pen 10 upward causes the telescopic column 8 to move inside the support column 7, compressing the elastic element 13. The detection pen 10 and the right-angle rod 3 pull the extension column 6 to the fixed column 7. The fixed column 5 moves inside, causing the extension column 6 to move the test pen 10 left and right via the right-angle rod 3. Then, the right-angle rod 3 is pushed to slide on the extension column 6 to adjust the position of the test pen 10 back and forth until the bottom of the test pen 10 is above the positive and negative terminals 12 of the battery 11. The test pen 10 is released, and through the rebound force of the elastic element 13, the elastic element 13 pushes the test end of the test pen 10 into the positive and negative terminals 12 of the battery 11 via the telescopic column 8. The other test pen 10 is operated in the same way. The main body 1 uses the test pen 10 to detect the resistance inside the battery 11, which achieves the supporting effect of the test pen 10 of the evaluation device. It eliminates the need for the staff to hold two different test pens 10 in each hand for testing, saving time and effort and effectively improving work efficiency.

[0028] Specifically, one end of the elastic element 13 is connected to the inside of the support column 7 by fasteners, and the other end of the elastic element 13 is connected to the end of the telescopic column 8 away from the buckle 9 by fasteners. The detection pen 10 is connected to the main body 1 through the line 2.

[0029] Through the above technical solution, the support column 7 is used to limit the telescopic column 8 and the elastic element 13, to prevent the telescopic column 8 from tilting when it moves the detection pen 10, and to prevent the elastic element 13 from shifting when it is squeezed. The buckle 9 is made of plastic, which makes it easy to lock and fix the detection pen 10.

[0030] Specifically, the back of the main body 1 is connected to one end of the positioning column 15 by fasteners, the outer wall of the positioning column 15 is connected to the rotating column 16 by rotation, and the inner outer wall of the rotating column 16 is connected to the bottom column 14 by a fixing plate.

[0031] Through the above technical solution, the positioning column 15 is used to support the rotating column 16, so that the rotating column 16 can rotate by the drive of the bottom column 14. At the same time, the positioning columns 15 are symmetrically distributed on the back of the main body 1. Through the top column 17 and the bottom column 14, this device can position drone batteries 11 of different sizes.

[0032] Specifically, the rotating column 16 and the bottom column 14 are connected to the bottom of the beveled rod 4 by fasteners in opposite directions, and the top of the beveled rod 4 is connected to the top column 17 by fasteners.

[0033] Through the above technical solution, the rotating column 16 can rotate on the positioning column 15. When the battery 11 applies pressure to the bottom column 14, the rotating column 16 will drive the inclined plate to rotate. The inclined plate will drive the top column 17 to abut against the side of the battery 11 to form a support and positioning effect for the battery 11.

[0034] Specifically, a battery 11 is provided on the bottom post 14. The battery 11 is located inside the top post 17. Positive and negative terminals 12 are provided at the bottom of the battery 11. The detection pen 10 is located at the positive and negative terminals 12 respectively.

[0035] Based on the above technical solution, the model of the subject 1 of this application is: FOXWELL BT705. The charging port of the drone battery 11 usually has multiple grooves, with positive and negative terminals 12 on both sides, and the through hole in the middle is the communication interface. During testing, two test pens 10 are placed on both sides of the charging port to "measure the AC internal resistance (ACIR) or DC internal resistance (DCIR) of the battery 11 at a specific frequency. Internal resistance is one of the most critical indicators of the battery 11's SOH, which will increase significantly with the increase of aging cycle number and storage degradation."

[0036] In use, first, place the battery 11 with the positive and negative terminals 12 facing downwards, and place the bottom of the battery 11 on the bottom post 14. The battery 11, by its own weight, pushes the bottom post 14 downwards, causing it to rotate on the positioning post 15 via the rotating post 16. The rotation of the rotating post 16 causes the angled plate to rotate, and the angled plate is pressed against the side of the battery 11 by the top post 17. The battery 11 is positioned by the bottom post 14 and the top post 17. The detection pen 10 is then installed on the buckle 9 via a snap-fit ​​mechanism. Pushing the detection pen 10 upwards causes the telescopic post 8 to move inside the support post 7, pressing against the elastic element 13. The right-angle rod 3 pulls the extension column 6 to move inside the fixed column 5, causing the extension column 6 to move the detection pen 10 left and right through the right-angle rod 3. Then, the right-angle rod 3 is pushed to slide on the extension column 6 to adjust the position of the detection pen 10 back and forth until the bottom of the detection pen 10 is above the positive and negative terminals 12 of the battery 11. The detection pen 10 is released, and through the rebound force of the elastic element 13, the elastic element 13 pushes the detection end of the detection pen 10 into the positive and negative terminals 12 of the battery 11 through the telescopic column 8. The other detection pen 10 is operated in the same way. The main body 1 detects the resistance inside the battery 11 through the detection pen 10, thus completing the work.
