Description

Technical Field

[0001] This invention relates to the field of power supply testing technology, specifically a load device for power supply testing. Background Technology

[0002] Power supply testing is a crucial step in ensuring the stable operation of power supply equipment and verifying whether its performance indicators meet requirements. Typically, the power supply is connected to a corresponding load device, which simulates different operating conditions of the power supply to conduct reliability tests. During testing, in order to verify the stability of the power supply under different temperature environments, the power supply is placed at different temperatures to conduct stability tests under low and high temperature environments. However, in high-temperature testing, if the power supply malfunctions, it is not easy to disconnect and isolate the power supply in a timely manner because the power supply is connected to the load device through conductivity, which is not conducive to high-temperature load testing of the power supply.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] 1. A conductive block two is fixedly connected to the sliding seat, allowing the power supply to be placed inside the test frame and connected to the terminal block via wires. After the test frame is inserted into the test chamber, conductive block one can be inserted into the fixed frame. Under the action of the return spring one, conductive block two abuts against conductive block one. Conductive block two is connected to the load tester inside the test chamber via wires, thus connecting the power supply to the electronic load for testing. Hot air is introduced into the test chamber through the conveying module to perform high-temperature load testing on the power supply. If the power supply malfunctions, the adjusting seat can be moved to the bottom of the corresponding sliding seat via the lifting mechanism one, and the sliding seat can be lifted by the abutting block, separating conductive block two from conductive block one, thereby cutting off the power supply. Furthermore, the test frame opening is blocked by a partition, isolating the power supply through the test frame and the partition, which is beneficial for high-temperature load testing of the power supply.

[0040] 2. The rotating seat has a three-way slot, and the height of the U-shaped seat can be adjusted by the lifting mechanism two. The drive motor drives the toothed sleeve to rotate, and the angle of the rotating seat can be adjusted as needed. Hot air can be introduced into the conveying pipe at the bottom of the conveying mechanism one. The hot air enters the three-way slot and then enters the rotating seat at the top through the fixed pipe. The hot air in the three-way slot can enter the test frame through the positioning pipe, thereby adjusting the temperature inside the test frame and performing high-temperature load testing on the power supply. The hot air in the test frame can enter the conveying mechanism two and be discharged from the conveying pipe at the bottom of the conveying mechanism two. At the same time, cold air can be introduced into the conveying pipe at the top of the conveying mechanism two. After passing through the top test frame, the cold air can be discharged through the conveying pipe at the top of the conveying mechanism one. The angle of the rotating seat can be adjusted as needed to make the three-way slot T-shaped. At this time, cold air and hot air can enter one test frame at the same time, thereby adjusting the temperature inside one test frame. Load testing of multiple power supplies at different temperatures is beneficial for testing the working stability of the power supply. Attached Figure Description

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Please see Figure 1-7 In this embodiment of the invention, a load device for power supply testing includes a test box 100. An electronic load is disposed inside the test box 100. A conductive block 242 is connected to the electronic load by a wire. The test box 100 is provided with a door panel 110, which is hinged and rotated on the test box 100. The door panel 110 has several observation windows, and a glass plate is fixedly connected inside the observation windows. A number of test frames 120 are disposed inside the test box 100, and a partition 130 fixedly connected to the test box 100 is disposed between two adjacent test frames 120 to separate the two adjacent test frames 120. A pull frame 122 is fixedly connected to the test frame 120 to facilitate pulling the test frame 120. An adjustment module 200 and a conveying module 300 are disposed inside the test box 100. A terminal block 123 is disposed inside the test frame 120, and a number of conductive blocks 124 are disposed on the terminal block 123.

[0057] The adjustment module 200 includes a fixed frame 210, which has several insertion slots 211 for inserting into adjacent conductive blocks 124. Inside the fixed frame 210, there is a lifting mechanism 220 and several positioning frames 240. Inside the positioning frames 240, there is a sliding seat 241. The sliding seat 241 is fixedly connected to several conductive blocks 242 that are in contact with adjacent conductive blocks 124. The sliding seat 241 is fixedly connected to several return springs 243 that are fixedly connected to the positioning frames 240. The lifting mechanism 220 is provided with an adjustment seat 230. The adjustment seat 230 is slidably connected to a sliding rod 231. Inside the adjustment seat 230, there is an electric telescopic rod. The output end of the electric telescopic rod is connected to the sliding rod 231. The sliding rod 231 is provided with an abutment block 232.

[0058] Specifically, the power supply can be placed inside the test frame 120 and connected to the terminal block 123 via wires. Then, the test frame 120 can be inserted into the test chamber 100. The test frame 120 can be supported by the partition 130. The first conductive block 124 can be inserted into the corresponding insertion slot 211. Under the action of the first reset spring 243, the second conductive block 242 abuts against the top of the first conductive block 124, making the first conductive block 124 and the second conductive block 242 conductive. The second conductive block 242 is connected to the load tester inside the test chamber 100 via wires, thereby connecting the power supply to the electronic load. The door panel 110 can be closed, and then the power supply can be tested by the electronic load. Hot air and cold air can be introduced into several test frames 120 through the delivery module 300 to perform high temperature and low temperature load tests on the power supply.

[0059] If the power supply malfunctions, the height of the adjusting seat 230 can be adjusted via the lifting mechanism 220 to move the adjusting seat 230 to the bottom of the corresponding sliding seat 241. Then, the sliding rod 231 can be moved by the electric telescopic rod 231 so that the abutment block 232 corresponds to the bottom of the sliding seat 241. The adjusting seat 230 can then be moved upward by the lifting mechanism 220. The adjusting seat 230 can then move the abutment block 232 upward by the sliding rod 231, thereby lifting the sliding seat 241. The sliding seat 241 can then move the conductive block 242 upward, separating the conductive block 242 from the conductive block 124, thus cutting off the power supply. The test frame 120 opening is blocked by the partition 130, and the test frame 120 and the partition 130 can isolate the power supply, which helps ensure the safety of the test and facilitates the smooth high-temperature load test of the power supply.

[0060] A temperature sensor can be embedded in the partition 130 to detect the temperature in the test frame 120 at its bottom, facilitating timely understanding of the test situation. When conducting high-temperature and high-load tests on the power supply, the adjusting seat 230 can be moved to the bottom of the corresponding sliding seat 241 in advance, allowing for timely power disconnection of the power supply in case of abnormalities. A water spray pipe can be installed inside the partition 130. If the temperature sensor detects an abnormal temperature rise and a fire risk, water can be sprayed into the test frame 120 through the water spray pipe, and finally, the staff can be reminded to pull out the test frame 120, which helps to improve the safety of the test.

[0061] Example 1

[0062] like Figure 5 As shown, in this embodiment, the lifting mechanism 220 includes a lifting frame 221, an adjusting screw 222, and a power motor 223;

[0063] Lifting frame 221 is fixedly connected inside the fixed frame 210. Adjusting seat 230 is slidably connected inside the lifting frame 221. Adjusting seat 230 can slide up and down inside the lifting frame 221. Adjusting screw 222 is rotatably connected inside the lifting frame 221. Adjusting screw 222 is screwed to the adjusting seat 230. Power motor 223 is fixedly connected inside the lifting frame 221. The output end of power motor 223 is drivenly connected to the bottom end of adjusting screw 222.

[0064] In practice, the adjusting screw 222 can be rotated by the power motor 223. When the adjusting screw 222 rotates, the adjusting seat 230 can be moved up or down along the lifting frame 221, thereby adjusting the height of the adjusting seat 230. By moving the adjusting seat 230 down to the bottom of the corresponding sliding seat 241, and then moving the adjusting seat 230 up to lift the sliding seat 241.

[0065] like Figure 4 , Figure 8 and Figure 9 As shown, in this embodiment, the test frame 120 has several connecting holes 121, the conveying module 300 includes a conveying mechanism 1 310 and a conveying mechanism 2 320 with the same structure, and the test box 100 is equipped with two fans, a heater and a cooler. The fans blow air through the heater or cooler, the heater heats the air to form hot air, and the cooler cools the air to form cold air.

[0066] The conveying mechanism 310 includes several conveying seats 311, several rotating seats 312, several three-way grooves 313, two conveying pipes 314, several fixed pipes 315, and several positioning pipes 316.

[0067] Several conveyor seats 311 are all set inside the test chamber 100. Several rotating seats 312 are rotatably connected to the several conveyor seats 311. Several three-way slots 313 are respectively opened inside the several rotating seats 312. Two conveying pipes 314 are respectively connected to adjacent rotating seats 312. The two conveying pipes 314 are respectively set on the rotating seats 312 located at the top and bottom. Several fixed pipes 315 are respectively connected to two adjacent conveyor seats 311, and the interiors of the two adjacent conveyor seats 311 are connected through the fixed pipes 315. Several positioning pipes 316 are respectively connected to several conveyor seats 311. The positioning pipes 316 are fixedly connected to the test chamber 100. The several positioning pipes 316 correspond one-to-one with several connecting holes 121.

[0068] The conveying module 300 also includes several connecting pipes 330. The connecting pipes 330 are connected to the conveying seats 311 of the first conveying mechanism 310 and the second conveying mechanism 320. The bottom end of the connecting pipe 330 is connected to the conveying seat 311 of the first conveying mechanism 310, and the top end of the connecting pipe 330 is connected to the conveying seat 311 of the second conveying mechanism 320. The height of the top end of the connecting pipe 330 is higher than the height of the bottom end of the connecting pipe 330.

[0069] In specific implementation, the angle of the rotating seat 312 can be adjusted as needed to adjust the top three-way groove 313 of the conveying mechanism 1 310 and the conveying mechanism 2 320 into an inverted T shape. The top conveying pipe 314 and the positioning pipe 316 are connected through the top three-way groove 313, and the bottom three-way groove 313 is adjusted into a right T shape. This allows the bottom conveying pipe 314 to be connected to the positioning pipe 316, and the fixed pipe 315 to be connected to the positioning pipe 316 through the three-way groove 313. Since the top three-way groove 313 is inverted T shape, the top three-way groove 313 and the bottom three-way groove 313 can be separated from each other, and the bottom three-way groove 313 is right T shape. The inside of the three-way groove 313 is separated from the inside of the connecting pipe 330.

[0070] Hot air can be introduced into the conveying pipe 314 at the bottom of the first conveying mechanism 310. The hot air can enter the three-way groove 313. The hot air in the three-way groove 313 can pass through the positioning pipe 316 and the connecting hole 121 into the test frame 120. The hot air in the three-way groove 313 can enter the rotating seat 312 at the top through the fixed pipe 315, so that the hot air enters several test frames 120 at the bottom, adjusts the temperature inside the test frame 120, and performs high-temperature load testing on the power supply. The hot air in the test frame 120 can enter the three-way groove 313 of the second conveying mechanism 320 through the connecting hole 121 and the positioning pipe 316, and then flow downward along the three-way groove 313 and the fixed pipe 315 of the second conveying mechanism 320, and finally exit from the conveying pipe 314 at the bottom of the second conveying mechanism 320.

[0071] Simultaneously, cold air can be introduced into the conveying pipe 314 at the top of the second conveying mechanism 320. The cold air can enter the test frame 120 at the top through the three-way groove 313 and the positioning pipe 316. The cold air in the test frame 120 can enter the three-way groove 313 of the first conveying mechanism 310 and then be discharged from the conveying pipe 314 at the top of the first conveying mechanism 310. This allows for high-temperature testing of the bottom test frames 120 and low-temperature testing of the top test frame 120. The rotating seat 312 at the same height as the first conveying mechanism 310 and the second conveying mechanism 320 can be adjusted so that the bottom three-way groove 313 is T-shaped and the top three-way grooves 313 are right-T-shaped. This allows for high-temperature testing of the bottom test frame 120 and low-temperature testing of the top test frames 120, which is beneficial for performing load tests on the power supply at different temperatures as needed.

[0072] After adjusting the top T-slots 313 of conveyor mechanism 1 310 and conveyor mechanism 2 320 into an inverted T-shape, and adjusting several bottom T-slots 313 into a right T-shape, the angle of the corresponding rotating seat 312 of conveyor mechanism 1 310 can be adjusted as needed to make the T-slots 313 T-shaped. This allows the top connecting pipe 330 to connect the T-shaped T-slots 313 of conveyor mechanism 2 320 with those of conveyor mechanism 1 310, allowing hot air to be introduced into the conveying pipe 314 at the bottom of conveyor mechanism 1 310 and into the conveying pipe 314 at the top of conveyor mechanism 2 320. When cold air is introduced, hot air can enter the T-shaped tee groove 313. The cold air in the inverted T-shaped tee groove 313 can enter the T-shaped tee groove 313 through the connecting pipe 330. Then, the mixed air can enter the corresponding test frame 120 through the positioning pipe 316, thereby adjusting the temperature inside the test frame 120. The mixed air in the test frame 120 can enter the rotating seat 312 of the second conveying mechanism 320, and finally follow the hot air out from the conveying pipe 314 at the bottom of the second conveying mechanism 320. This facilitates load testing of multiple power supplies at different temperatures and is beneficial for testing the working stability of the power supply.

[0073] Example 2

[0074] Based on Example 1, such as Figure 11 and Figure 13 As shown, in this embodiment, the conveying module 300 further includes a second lifting mechanism 340 and several linkage mechanisms 360. The linkage mechanism 360 is disposed between the conveying seat 311 of the first conveying mechanism 310 and the second conveying mechanism 320. The rotating seat 312 of the first conveying mechanism 310 and the second conveying mechanism 320 are linked by the linkage mechanism 360. The second lifting mechanism 340 is disposed inside the test box 100. The second lifting mechanism 340 is provided with a U-shaped seat 350. The second lifting mechanism 340 is used to adjust the height of the U-shaped seat 350. The U-shaped seat 350 is provided with a drive frame 351. The drive frame 351 is fixedly connected to the drive motor 353. The output end of the drive motor 353 is connected to a toothed sleeve 354. The rotating seat 312 is fixedly connected with a toothed block 317 that is rotatably connected to the conveying seat 311. The edge of the toothed block 317 and the inner edge of the toothed sleeve 354 are both provided with arc surfaces to facilitate the engagement of the toothed block 317 and the toothed sleeve 354.

[0075] The drive frame 351 is slidably connected to a sliding frame 352 that is slidably connected to the U-shaped seat 350. The drive frame 351 can move up and down along the sliding frame 352. The sliding frame 352 is fixedly connected to a plurality of return springs 357 that are fixedly connected to the drive frame 351. The return springs 357 can support the drive frame 351. The sliding frame 352 is fixedly connected to a limiting block 356 that is slidably connected to the U-shaped seat 350. The limiting block 356 and the sliding frame 352 can move horizontally along the inside of the U-shaped seat 350. The U-shaped seat 350 is provided with an electric telescopic rod 2. The output end of the electric telescopic rod 2 is connected to the adjacent limiting block 356. The conveying seat 311 is fixedly connected to a plurality of plug-in seats 370. The drive frame 351 is fixedly connected to a plurality of plug-in rods 355 that are slidably connected to the inside of the adjacent plug-in seats 370. The plug-in rods 355 have pointed sides to facilitate insertion of the plug-in rods 355 into the plug-in seats 370.

[0076] In practice, the U-shaped seat 350 can be moved to the corresponding height by the lifting mechanism 340. Then, the bottom limiting block 356 can be moved by the electric telescopic rod 2. The limiting block 356 can drive the sliding frame 352 to move, the sliding frame 352 can drive the drive frame 351 to move, and the drive frame 351 can drive the drive motor 353 and the toothed sleeve 354 to move, so that the toothed sleeve 354 is fitted onto the corresponding toothed block 317, thereby engaging the toothed block 317 inside the toothed sleeve 354, and causing the insertion rod 355 to be inserted into the corresponding insertion seat 370, so that the drive frame 351 moves up or down along the sliding frame 352. The toothed sleeve 354 is aligned and engaged with the toothed block 317, while limiting the height of the drive frame 351. Then, the toothed sleeve 354 can be rotated by the drive motor 353. The toothed sleeve 354 can rotate the toothed block 317, which can rotate the rotating seat 312 of the first conveyor mechanism 310. The rotating seat 312 of the first conveyor mechanism 310 can be rotated by the linkage mechanism 360, thereby adjusting the angle between the rotating seats 312 of the first conveyor mechanism 310 and the second conveyor mechanism 320, so as to facilitate high temperature or low temperature load testing of the power supply as needed.

[0077] After adjustment, the limit block 356 can be moved in the opposite direction by the electric telescopic rod 2, so that the limit block 356 drives the drive frame 351 to move in the opposite direction through the sliding frame 352, so that the tooth sleeve 354 is disengaged from the tooth block 317, and the plug rod 355 is disengaged from the plug seat 370.

[0078] like Figure 10 As shown, in this embodiment, the linkage mechanism 360 includes linkage rod one 361, linkage rod two 362, positioning ring 363, one-way bearing 364, ratchet block one 365, ratchet block two 366, and return spring three 367.

[0079] Linkage rod 361 is rotatably connected to the conveyor seat 311 of conveyor mechanism 310, and is fixedly connected to the rotating seat 312 of conveyor mechanism 310. Linkage rod 362 is rotatably connected to the conveyor seat 311 of conveyor mechanism 320, and is fixedly connected to the rotating seat 312 of conveyor mechanism 320. Linkage rod 361 and linkage rod 362 are rotatably connected. Positioning ring 363 is fixedly connected to the conveyor seat 311 of conveyor mechanism 320. One-way bearing 364 is disposed inside positioning ring 363 and is fixedly sleeved on linkage rod 362. Ratchet teeth Block 1 365 is slidably connected inside linkage rod 1 361. Linkage rod 1 361 has a locking groove inside. A locking block that is slidably connected to the locking groove is fixedly connected to ratchet block 1 365. The locking block can move along the inside of the locking groove, so that ratchet block 1 365 only slides inside linkage rod 1 361. Racket block 2 366 is fixedly connected to linkage rod 2 362. Racket block 1 365 and ratchet block 2 366 mesh with each other. Return spring 3 367 is fixedly connected inside linkage rod 1 361 and to ratchet block 1 365. Under the action of return spring 3 367, ratchet block 1 365 and ratchet block 2 366 can be kept meshed.

[0080] In specific implementation, when the drive motor 353 drives the tooth block 317 to rotate through the tooth sleeve 354, causing the rotating seat 312 of the first conveyor mechanism 310 to rotate in the forward direction, the rotating seat 312 of the first conveyor mechanism 310 can drive the linkage rod 361 to rotate. The linkage rod 361 can drive the ratchet block 365 to rotate through the locking block. The ratchet block 365 can drive the ratchet block 366 to rotate. The ratchet block 366 can drive the linkage rod 362 to rotate, causing the linkage rod 362 to rotate in the one-way bearing 364. The linkage rod 362 can drive the rotating seat 312 of the second conveyor mechanism 320 to rotate, thereby causing the rotating seats 312 of the first conveyor mechanism 310 and the second conveyor mechanism 320 to rotate synchronously. Adjust the angle of the rotating seats 312 at the same height as the first conveyor mechanism 310 and the second conveyor mechanism 320 so that the three-way groove 313 is inverted T-shaped or right T-shaped.

[0081] As needed, the drive motor 353 can be used to reverse the rotation of the toothed sleeve 354, thereby causing the toothed block 317 to drive the rotating seat 312 of the first conveyor mechanism 310 to rotate in the opposite direction. The angle of the three-way groove 313 in the rotating seat 312 is adjusted to a T-shape. When the rotating seat 312 drives the first linkage rod 361 to rotate in the opposite direction, since the first ratchet block 365 only drives the second ratchet block 366 to rotate in one direction, the first linkage rod 361 will not drive the second ratchet block 366 to rotate through the first ratchet block 365, and thus will not drive the second linkage rod 362 to rotate. Moreover, the positioning ring 363 can prevent the second linkage rod 362 from rotating in the opposite direction through the one-way bearing 364. In this way, only the angle of the rotating seat 312 of the first conveyor mechanism 310 will be adjusted, and the inverted T-shaped three-way groove 313 of the second conveyor mechanism 320 will be connected to the T-shaped three-way groove 313 of the first conveyor mechanism 310 through the top connecting pipe 330.

[0082] like Figure 11 As shown, in this embodiment, the second lifting mechanism 340 includes a second lifting frame 341, a second power motor 342, a second adjusting screw 343, and a lifting block 344;

[0083] Lifting frame 2 341 is fixedly connected inside the test chamber 100. Power motor 2 342 is fixedly connected to the bottom of lifting frame 2 341. Adjusting screw 2 343 is rotatably connected inside lifting frame 2 341. The output end of power motor 2 342 is connected to the bottom end of adjusting screw 2 343. Lifting block 344 is slidably connected inside lifting frame 2 341. Lifting block 344 can move up and down along the inside of lifting frame 2 341. The inside of lifting block 344 is screwed to adjusting screw 2 343. Lifting block 344 is fixedly connected to U-shaped seat 350.

[0084] In practice, the adjustment screw 343 can be rotated by the power motor 342. The rotation of the adjustment screw 343 can cause the lifting block 344 to move up or down along the inside of the lifting frame 341. The lifting block 344 can drive the U-shaped seat 350 to move, and then move the U-shaped seat 350 to the side of the corresponding toothed block 317, and adjust the angle of the corresponding rotating seat 312.

[0085] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
