Description

Technical Field

[0001] The present invention relates to the technical field of aging detection, and in particular to an aging detection device for a PD mobile power supply. Background Art

[0002] Aging testing of PD power banks is essential. First, during the production process, PD power banks may contain some potential defects due to variations in component quality and fluctuations in production processes. These defects may not be apparent in the initial stages of normal use, but with increased usage and charge and discharge cycles, problems will gradually become apparent, such as reduced charging efficiency, inability to output power normally, and even safety hazards. Aging testing, by simulating long-term, high-load usage scenarios, can screen out these potential defective products in advance, preventing them from entering the market and endangering users. Second, PD power banks are used in diverse scenarios and in complex and changing environments, including varying temperatures, humidity levels, and frequent plugging and unplugging. Aging testing can simulate these complex environments and verify the performance stability and reliability of the power bank under various conditions, ensuring its continued stable operation in actual use and ensuring user charging needs and safety. Third, with the rapid development of PD technology, power bank functions are becoming increasingly complex. Features such as multi-speed PDO output increase the risk of product failure. Aging testing can comprehensively evaluate the overall performance of the product, ensuring that it meets quality standards and user expectations, thereby improving product quality and enhancing brand competitiveness.

[0003] However, in existing PD mobile power bank aging detection equipment, the PD mobile power bank is tested at different extreme temperatures during the aging test, causing the PD mobile power bank to expand. Traditional clamping structures often have difficulty flexibly adjusting the spacing between the clamping plates according to the diverse shapes and models of PD mobile power banks, resulting in the inability to effectively clamp and fix PD mobile power banks of different models. PD mobile power banks are prone to unstable electrical connections, and the detection effect is single, making it difficult to simultaneously achieve efficient and diverse detection results. Summary of the Invention

[0004] To address the problem that the conventional clamping structure proposed in the background art is often difficult to flexibly adjust the spacing between the clamping plates according to the various shapes and models of PD mobile power supplies, resulting in the inability to effectively clamp and fix different models of PD mobile power supplies, the present invention provides an aging detection device for PD mobile power supplies, which includes:

[0005] A cabinet body, wherein a plurality of clamping parts are installed inside the cabinet body, and a heat dissipation part is installed outside the cabinet body;

[0006] The clamping part is used to clamp and fix multiple groups of PD mobile power supplies, and then the mobile power supplies are subjected to aging detection through the detection mechanism. The heat dissipation part is used to circulate the cabinet and external air to simulate various working conditions in actual use environments.

[0007] The clamping part includes:

[0008] There are three detection boxes, which are used to carry out detection of PD mobile power supplies of different sizes and models respectively. The left sides of the three detection boxes are fixedly connected to motor 1, and the output ends of the three motors 1 are fixedly connected to bidirectional threaded rods through couplings. The three bidirectional threaded rods rotate and pass through the three detection boxes respectively. The inner walls of the three detection boxes are fixedly connected to sliding rods, and the outer walls of the three bidirectional threaded rods are threadedly connected to two push blocks, and several push blocks are slidably connected to the outer walls of the three sliding rods respectively.

[0009] Preferably, the outer walls of the three sliding rods are slidably connected to a plurality of splints, and the plurality of splints are fixedly connected to sliders. The three groups of sliders are respectively fixedly connected to springs 1, and the plurality of springs 1 are respectively wound around the outer walls of the three sliding rods.

[0010] Preferably, a heat-insulating cavity 1 is opened inside the three detection boxes, and the inner walls of the three heat-insulating cavities 1 are coated with a heat-insulating layer. The detection mechanism includes several PCB detection boards fixed on the inner wall of the heat-insulating cavity 1, and several of the PCB detection boards are provided with data lines, and several of the data lines extend to the interior of the detection box.

[0011] Preferably, a connector is provided on one end of each of the data lines away from the PCB detection board, and a door is hinged on the front side of each of the three detection boxes;

[0012] Among them, the connector is used to be inserted into the interface of the PD mobile power supply and cooperate with the PCB detection board to perform aging detection on the PD mobile power supply.

[0013] Preferably, the tops of several of the detection boxes are fixedly connected to a pressure detection plate, the sides of the two push blocks close to each other are hinged with hinged rods, the bottom ends of the two hinged rods are hinged with a movable plate, and the inner wall of the detection box is fixedly connected to two connecting rods 1, and the two connecting rods 1 slide through the movable plate.

[0014] Preferably, several connecting rods 2 are passed through the movable plate, the bottom ends of several connecting rods 2 are fixedly connected to pressure plates, several pressure plates are respectively located above several joints, and the outer walls of several connecting rods 2 are wrapped with springs 2, one end of the spring 2 is fixedly connected to the movable plate, and the other end of the spring 2 is fixedly connected to the pressure plate.

[0015] On this basis, since the existing devices are difficult to promote the rapid and sufficient circulation of air inside the detection box and the outside world, the heat exchange process is slow and the heat exchange efficiency in different detection boxes is uneven. In order to improve the heat exchange efficiency.

[0016] Preferably, the heat dissipation unit includes:

[0017] A fixed frame is fixedly mounted on the inner wall of the cabinet, the heat dissipation portion is used to heat the PD mobile power supply with hot air, the fixed frame is used to carry three test boxes, an insulating cavity 2 is provided between the fixed frame and the left inner wall of the cabinet, the inner wall of the insulating cavity 2 is coated with an insulating layer, and the three motors 1 are all located inside the insulating cavity 2 to protect and separate the three motors 1.

[0018] Preferably, a heating chamber is provided at the bottom of the three detection boxes, a resistance wire is fixedly connected to the inner wall of the three heating chambers, an air inlet is provided on the rear side of the three heating chambers, an air guide port is provided at the inner bottom of the three detection boxes, an air outlet is provided on the right side of the three detection boxes, a fan casing is connected to the right side of the cabinet, a motor 2 is fixedly connected to the rear side of the fan casing, the output end of the motor 2 is fixedly connected to a rotating rod through a coupling, and the outer wall of the rotating rod is fixedly connected to an impeller.

[0019] As a further improvement of the present technical solution, by providing a fixed frame and an air outlet, when the driving motor 2 drives the rotating rod and the impeller to rotate, the air inside the multiple test boxes is circulated with the external air, thereby performing synchronous heat exchange inside the multiple test boxes.

[0020] In another solution, it is difficult to achieve targeted heating of PD mobile power supplies in different test boxes to meet the needs of aging testing of different body types in different environments.

[0021] As a further improvement of the present technical solution, a heat dissipation part is provided. When the resistance wire is driven to heat the air inside the heating chamber, the impeller rotates to introduce the external air into the heating chamber through the air inlet in turn for heating, and then introduces it into the interior of the test box through the air guide port, so that the PD mobile power supplies inside the three test boxes can be heated by hot air, and the heated air is discharged through the air outlet. The three test boxes are heated independently in turn.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. By providing a clamping part, when the driving motor drives the bidirectional threaded rod to rotate, the two push blocks are moved closer to or away from each other with the cooperation of the slide bar. When the two push blocks approach each other and squeeze the two sliders at the edge, the two sliders on the left and right are driven to approach each other, so that multiple sliders squeeze multiple springs. After multiple PD mobile power supplies are placed between multiple clamping plates, the multiple sliders move closer to each other to clamp and fix the PD mobile power supplies. At the same time, after multiple connectors are inserted into multiple PD mobile power supplies, the PD mobile power supplies are tested for aging in cooperation with the PCB test board. The device can adjust the spacing between the multiple clamping plates according to the size and model of the PD mobile power supplies, and thus can test multiple PD mobile power supplies. A group of different types of PD mobile power supplies are clamped and fixed to ensure that the PD mobile power supplies can maintain stable electrical connection and mechanical fixation during the aging test, thereby improving the accuracy and reliability of the aging test. When the two push blocks approach each other, the cooperation of the two hinged rods and the limiting action of the two connecting rods can squeeze the movable plate downward, so that the pressure plate can fit on the top of the PD mobile power supply. When the PD mobile power supply expands during detection in a high temperature environment, it will squeeze the pressure plate upward. At this time, the spring two will be compressed, and the connecting rod two will support the pressure detection plate, so that the pressure detection plate can detect the expansion amplitude, thereby effectively protecting and controlling the detection process of the PD mobile power supply.

[0024] 2. By providing a fixed frame and an air outlet, when the driving motor 2 drives the rotating rod and the impeller to rotate, the air inside the multiple test boxes is circulated with the external air, thereby exchanging heat inside the multiple test boxes, improving the heat exchange efficiency inside different test boxes, and ensuring that the test boxes can reach the specified test temperature in a short time.

[0025] 3. By providing a heat dissipation part, when the resistance wire is driven to heat the air inside the heating chamber, the impeller rotates to introduce the external air into the heating chamber through the air inlet in turn for heating, and then introduces it into the interior of the test box through the air guide port, so that the PD mobile power supplies inside the three test boxes can be heated by hot air, and the heated air is discharged through the air outlet. The three test boxes are heated independently in turn, so that three groups of PD mobile power supplies of different sizes can be tested for aging in different environments, and the comparison of data can improve the accuracy and efficiency of aging detection.

The three groups of sliders 221 are respectively fixedly connected to springs 222, and the plurality of springs 222 are respectively wound around the outer walls of the three slide bars 213.

[0052] like Figure 6 and Figure 9As shown, each of the three test boxes 21 has an insulating cavity 23 formed therein. The inner walls of the three insulating cavities 23 are coated with an insulating layer. The test mechanism includes a plurality of PCB test boards 231 fixed to the inner walls of the insulating cavity 23. Each of the PCB test boards 231 is provided with a data line 232. The data lines 232 extend into the interior of the test box 21. The ends of the data lines 232 away from the PCB test boards 231 are provided with connectors 233. The front sides of the three test boxes 21 are hinged with a door 24.

[0053] The connector 233 is used to be inserted into the interface of the PD mobile power supply and cooperate with the PCB detection board 231 to perform aging detection on the PD mobile power supply.

[0054] The tops of the several detection boxes 21 are fixedly connected to the pressure detection plates 25, the sides of the two push blocks 214 close to each other are hinged with hinged rods 251, the bottom ends of the two hinged rods 251 are hinged with movable plates 252, the inner wall of the detection box 21 is fixedly connected to two connecting rods 1 253, the two connecting rods 1 253 are slidably passed through the movable plate 252, the movable plate 252 is penetrated by several connecting rods 254, the bottom ends of several connecting rods 254 are fixedly connected to pressure plates 255, several pressure plates 255 are respectively located above the several joints 233, the outer walls of several connecting rods 254 are wound with springs 256, one end of the spring 256 is fixedly connected to the movable plate 252, and the other end of the spring 256 is fixedly connected to the pressure plate 255;

[0055] Among them, when the two push blocks 214 approach each other, under the cooperation of the two hinged rods 251 and the limiting action of the two connecting rods 253, the movable plate 252 can be squeezed to move downward, so that the pressure plate 255 can be attached to the top of the PD mobile power supply. When the PD mobile power supply is detected to expand under a high temperature environment, the pressure plate 255 will be squeezed to move upward. At this time, the spring 256 will be compressed, and the connecting rod 254 will support the pressure detection plate 25, so that the pressure detection plate 25 can detect the expansion amplitude.

[0056] like Figure 2-Figure 5 As shown, the heat dissipation unit 3 includes:

[0057] A fixing frame 31 is fixedly mounted on the inner wall of the cabinet 1. The three detection boxes 21 are fixedly connected to the inner wall of the fixing frame 31. The fixing frame 31 is used to carry the three detection boxes 21. A second heat insulation cavity 32 is provided between the fixing frame 31 and the left inner wall of the cabinet 1. The inner wall of the second heat insulation cavity 32 is coated with a heat insulation layer. The three motors 1 211 are all located inside the second heat insulation cavity 32 to protect and separate the three motors 1 211. A heating cavity 33 is provided at the bottom of the three detection boxes 21. The inner walls of the three heating cavities 33 are fixedly connected to resistance wires 331. The rear sides of the three heating cavities 33 are provided with air inlets 332. The inner bottoms of the three detection boxes 21 are provided with air guide ports 333. The right sides of the three detection boxes 21 are provided with air outlets 34.

[0058] The plurality of resistance wires 331 inside the heating chamber 33 can heat the air inside the heating chamber 33;

[0059] like Figure 7 As shown, the right side of the cabinet 1 is connected to a fan housing 341, and a second motor 342 is fixedly connected to the rear side of the fan housing 341. The output end of the second motor 342 is fixedly connected to a rotating rod 343 through a coupling, and the outer wall of the rotating rod 343 is fixedly connected to an impeller 344;

[0060] The second motor 342 can drive the rotating rod 343 and the impeller 344 to rotate, thereby extracting the air inside the cabinet 1 .

[0061] Step 1: The driving motor 1 211 drives the bidirectional threaded rod 212 to rotate, and with the cooperation of the slide bar 213, the two push blocks 214 are moved closer to or away from each other. When the two push blocks 214 move closer to each other and squeeze the two sliders 221 at the edge, the two sliders 221 on the left and right are driven closer to each other, so that the multiple sliders 221 squeeze the multiple springs 1 222. After the multiple PD mobile power supplies are placed between the multiple clamping plates 22, the multiple sliders 221 move closer to each other to clamp and fix the PD mobile power supplies, ensuring that the PD mobile power supplies are in good condition during the aging test. During the aging test, stable electrical connection and mechanical fixation can be guaranteed, thereby improving the accuracy and reliability of the aging test. Under the cooperation of the two hinged rods 251 and the limiting action of the two connecting rods 253, the movable plate 252 can be squeezed to move downward, so that the pressure plate 255 can be attached to the top of the PD mobile power supply. When the PD mobile power supply is expanded during detection in a high temperature environment, the pressure plate 255 will be squeezed to move upward. At this time, the spring 256 will be compressed, and the connecting rod 254 will support the pressure detection plate 25, so that the pressure detection plate 25 can detect the expansion amplitude.

[0062] Step 2: Driving motor 2 342 drives the rotating rod 343 and the impeller 344 to rotate, so that the air inside the multiple test boxes 21 is circulated with the external air, thereby performing heat exchange inside the multiple test boxes 21, improving the heat exchange efficiency inside different test boxes 21, and ensuring that the test boxes 21 can reach the specified test temperature in a short time.

[0063] The third step: During operation, the resistance wire 331 is driven to heat the air inside the heating chamber 33. The impeller 344 rotates to introduce the external air into the heating chamber 33 through the air inlet 332 for heating, and then introduces the air into the testing box 21 through the air guide 333, so that the PD mobile power supplies inside the three testing boxes 21 can be heated by hot air. The heated air is discharged through the air outlet 34. The three testing boxes 21 are heated independently in turn, so that three groups of PD mobile power supplies of different sizes can be tested for aging in different environments, and the comparison of data improves the accuracy and efficiency of aging testing.

[0064] Working principle: by providing a clamping part 2, when the driving motor 211 drives the bidirectional threaded rod 212 to rotate, the two push blocks 214 are moved closer to or away from each other with the cooperation of the slide bar 213. When the two push blocks 214 move closer to each other and squeeze the two sliders 221 at the edge, the two sliders 221 on the left and right are driven to move closer to each other, so that the multiple sliders 221 squeeze the multiple springs 222. After placing multiple PD mobile power supplies between multiple splints 22 respectively, the multiple sliders 221 move closer to each other to clamp and fix the PD mobile power supplies. At the same time, after inserting multiple connectors 233 into multiple PD mobile power supplies respectively, the PD mobile power supplies are tested for aging in cooperation with the PCB detection board 231. The device can adjust the spacing between the multiple splints 22 according to the size and model of the PD mobile power supplies. The PD mobile power supply 214 is integrated, and thus multiple groups of different models of PD mobile power supplies can be clamped and fixed, ensuring that the PD mobile power supply can maintain stable electrical connection and mechanical fixation during the aging test, thereby improving the accuracy and reliability of the aging test. When the two push blocks 214 approach each other, under the cooperation of the two hinged rods 251 and the limiting action of the two connecting rods 253, the movable plate 252 can be squeezed to move downward, thereby allowing the pressure plate 255 to fit on the top of the PD mobile power supply. When the PD mobile power supply expands during detection in a high temperature environment, the pressure plate 255 will be squeezed to move upward. At this time, the spring 256 will be compressed, and the connecting rod 254 will support the pressure detection plate 25, so that the pressure detection plate 25 can detect the expansion amplitude, thereby effectively protecting and controlling the detection process of the PD mobile power supply.

[0065] By providing the fixing frame 31 and the air outlet 34, when the second driving motor 342 drives the rotating rod 343 and the impeller 344 to rotate, the air inside the multiple test boxes 21 is circulated with the external air, thereby performing heat exchange inside the multiple test boxes 21, improving the heat exchange efficiency inside the different test boxes 21, and ensuring that the test boxes 21 can reach the specified test temperature in a short time;

[0066] By providing a heat dissipation part 3, when the resistance wire 331 is driven to heat the air inside the heating chamber 33, the impeller 344 rotates to introduce the external air into the heating chamber 33 through the air inlet 332 in turn for heating, and introduces it into the interior of the detection box 21 through the air guide port 333, so that the PD mobile power supplies inside the three detection boxes 21 can be heated by hot air, and the heated air is discharged through the air outlet 34. The three detection boxes 21 are heated independently in turn, so that three groups of PD mobile power supplies of different sizes can be tested for aging in different environments, and the comparison data can improve the accuracy and efficiency of the aging test.
