[0002] The power supply tester can fully test the electrical performance of the power supply, including but not limited to key parameters such as voltage, current, power, efficiency, etc. This helps to ensure that the output of the power supply meets the design requirements, can detect the stability and reliability of the power supply, and promptly discover potential problems and faults, thereby improving the overall quality of the power supply.

[0003] In the existing public documents, the patent announcement number CN117452274A discloses a power supply test device with automatic switching of multiple power supplies, which is used to deliver the power supply to be tested to the battery test box, or take out the power supply to be tested in the battery test box after the test has been completed in the battery test box; the test body component is used to clamp the power supply to be tested in the battery test box after the transport component delivers the power supply to be tested to the battery test box, and test the power supply to be tested; after the test is completed, the battery test box is released, so that the transport component takes out the power supply to be tested in the battery test box after the test has been completed. The device has a simple structure and is convenient and fast; however, the patent has the following defects.

[0004] When the power supply testing device tests multiple power supply groups, it is necessary to connect the terminals of the power supply to the test ends of the testing equipment. However, during the mobile docking process, the inner spacing between the multiple power supply groups is difficult to maintain at the specified distance for docking. At the same time, during the movement of the multiple power supply groups, their outer spacing is difficult to maintain at the specified distance for docking. At the same time, it is also difficult to achieve precise positioning and docking tests at the ends of the multiple power supply groups according to the specified extrusion pressure. This causes the docking of the multiple power supply groups to be offset, the reinforcement effect is poor and it will cause looseness, making it difficult for the multiple power supply groups under test to achieve multi-directional precise positioning and fixed force docking tests, thereby the accuracy of the multiple power supply test is poor. For this reason, a reinforced multiple power supply testing device is needed. Summary of the invention

[0036] The working principle of the reinforced multi-group power supply test device of the present invention is as follows:

[0037] First, when the present invention performs the internal interval positioning docking test, the wiring harness of the electrical equipment is first docked on the output terminal 17, the charging device is plugged on the input terminal 16, and the data line port 18 is docked on the background computer through the data line. The internal interval distance between the two tested power supply groups 2 is set by the controller 13, so that the driving motor 24 is started by the controller 13, the driving motor 24 drives the linkage screw 23 to rotate, and the linkage screw 23 drives the socket block 25 to move right under the action of the thread transmission force, and at the same time, the socket block 25 drives the internal interval distance sensor 26 to move right, and another socket block 25 moves left under the action of the thread transmission force, and another socket block 25 drives the internal sensing block 27 to move left.

[0038] At the same time, the socket block 25 drives the connecting strip 28 to move right, and the connecting strip 28 drives the positioning inner plate 29 to move right, while the other positioning inner plate 29 moves left, and the distance sensing of the inner sensing block 27 is realized through the inner interval distance sensor 26. When the distance value sensed by the inner interval distance sensor 26 is the same as the inner interval distance set by the controller 13, the distance between the right side surface of the positioning inner plate 29 and the left side surface of the other positioning inner plate 29 is the specified distance value, so that the controller 13 immediately turns off the drive motor 24.

[0039] Secondly, when the present invention performs an external spacing positioning docking test, the external spacing distance values ​​of the two tested power supply groups 2 are set on the controller 13 at the same time, and the transmission motor 30 is started by the controller 13, and the transmission motor 30 drives the bidirectional screw 36 to rotate, and the bidirectional screw 36 drives the two threaded sleeves 35 to approach each other under the action of the thread transmission force, and the threaded sleeve 35 moves to the left along the inner wall of the guide frame 22, and the other threaded sleeve 35 moves to the right.

[0040] At the same time, the threaded sleeve 35 drives the outer spacing distance sensor 31 to move left, and the other threaded sleeve 35 drives the outer sensing block 32 to move right, so that the threaded sleeve 35 drives the outer positioning bar 33 to move left, the outer positioning bar 33 drives the positioning support bar 34 to move left, and the other positioning support bar 34 to move right. The distance sensing of the outer sensing block 32 is realized by the outer spacing distance sensor 31. When the distance value sensed by the outer spacing distance sensor 31 is the same as the outer spacing distance value set on the controller 13, the transmission motor 30 is turned off by the controller 13, so that the outer distance between the two positioning support bars 34 can be accurately positioned. Then one group of the tested power supply groups 2 is inserted into the positioning gap between the positioning support bar 34 and the positioning inner plate 29, and another group of the tested power supply groups 2 is inserted into the positioning gap between another positioning support bar 34 and another positioning inner plate 29.

[0041] Then, when the present invention performs an end positioning and fixed force docking test, the support frame 4 is supported by the positioning frame 1, the controller 13 starts the reduction motor 6, the reduction motor 6 drives the screw 5 to rotate, and the screw 5 drives the sleeve block 7 to move right under the action of the thread transmission force, so that the sleeve block 7 moves right along the inner wall of the support frame 4, the sleeve block 7 makes the two connecting rods 8 move right synchronously, the two connecting rods 8 move right along the inside of the support frame 4, the two connecting rods 8 drive the locking frame 10 to move right, the locking frame 10 drives multiple concave positioning blocks 11 to move right, the inner walls of the multiple concave positioning blocks 11 in the front are inserted at the end position of the power supply group 2 under test, and the inner walls of the multiple concave positioning blocks 11 in the rear are inserted at the end position of another power supply group 2 under test.

[0042] The power supply group 2 under test can be moved rightward along the precise position between the positioning support bar 34 and the positioning inner plate 29, and the power supply group 2 under test drives the multiple test terminals 19 to be precisely plugged into the docking holes of the docking test circuit board 3. At the same time, the support 12 supports the torque sensor 9, which senses the torque of the screw 5. When the torque sensed by the torque sensor 9 is the same as the torque set by the controller 13, the reduction motor 6 is turned off by the controller 13, so that the two power supply groups 2 under test can be precisely positioned and fixed with the test terminals 19 and the docking test circuit board 3 according to the specified extrusion force.

[0043] Finally, when the present invention performs a test display, power is supplied to the test terminal 19 through the power supply group 2 under test, and the test terminal 19 supplies power to the docking test circuit board 3, and the docking test circuit board 3 supplies power to the power-consuming device through the output terminal 17, and current and voltage sensing is performed through the current and voltage detection probe 20 on the output terminal 17 to check whether the output current and voltage of the power supply group 2 under test in normal use are the same as the current and voltage set by the controller 13. At the same time, the input terminal 16 can supply charging current to the docking test circuit board 3, and the docking test circuit board 3 supplies it to the power supply group 2 under test, and check whether the power supply current and voltage of the input terminal 16 can be within the range set by the controller 13, and the input and output current and voltage data are displayed on the display screen 15, and the cooling fan 14 is started at the same time. The cooling fan 14 can realize heat dissipation operation inside the positioning frame 1, and can realize test operation on multiple groups of power supply groups 2 under test.
