[0066] When the X1 battery needs to be tested, switch T1 is operated, and then test circuit Y1 is executed;
[0067] When the X2 battery needs to be tested, switch T2 is operated, and then test circuit Y2 is executed;
[0068] When the X3 battery needs to be tested, switch T3 is operated, and then test circuit Y3 is executed;
[0069] An error will occur if two or more trigger switches 3 are pressed simultaneously.
[0070] Therefore, the multi-purpose battery testing equipment provided by this utility model can effectively solve the problem of poor compatibility of existing testing equipment with different battery models, resulting in excessively high testing costs.
[0071] In this embodiment, the fixture base 1 includes:
[0072] An insulating base 101 is provided with a contour mounting groove 1011 for the detachable contouring component 2 to be slidably inserted laterally.
[0073] A fixed metal plate 102 is fixed to the groove wall of the contour part mounting groove 1011, with one end extending into the contour part mounting groove 1011 and the other end electrically connected to the test motherboard.
[0074] Accordingly, the detachable contouring component 2 includes:
[0075] The contouring body 201 has a battery mounting groove 2011 on its top surface and a metal plate slot 2013 for inserting the fixed metal plate 102 on the surface opposite to the contouring body 201.
[0076] A movable metal spring 202 has one end extending into the battery mounting slot 2011 to electrically connect to the battery under test; the other end of the movable metal spring 202 extends into the metal plate slot 2013 to electrically connect to the fixed metal plate 102 inserted into the metal plate slot 2013.
[0077] In this embodiment, the side of the contouring body 201 is provided with a guide slot 2012, wherein the length direction of the guide slot 2012 is parallel to the insertion and removal direction of the fixing metal plate 102 and the metal plate slot 2013.
[0078] Accordingly, the insulating base 101 is provided with a limiting insert 1012 that extends into the guide slot 2012 to restrict the upward movement of the contour body 201 relative to the insulating base 101.
[0079] Optionally, the surface of the contouring body 201 opposite to the fixed metal sheet 102 is also provided with a movable magnet 203, and the surface of the insulating base 101 on which the fixed metal sheet 102 is provided with a fixed magnet 103.
[0080] The fixed magnet 103 has a magnetic polarity opposite to that of the movable magnet 203, so as to restrict the sliding of the detachable contour piece 2 away from the fixed metal piece 102 by magnetic attraction.
[0081] The multi-purpose battery testing equipment provided in this embodiment operates in the following detailed manner:
[0082] I. Installation and Mechanical Positioning of Copying Parts
[0083] 1. Horizontal sliding insertion
[0084] The operator slides the detachable profile 2 into the insulating base 101 along the lateral direction of the profile mounting groove 1011.
[0085] During this process, the guide slot 2012 cooperates with the limiting insert 1012 on the fixture base 1, which not only guides the copying part to be accurately inserted along the preset path to avoid deviation or tilting, but also prevents the copying part from moving upward, ensuring that the copying part will not be removed from the base due to external force during the test.
[0086] 2. Magnetic-assisted fixation
[0087] When the copying part is inserted into place, the movable magnet 203 on the copying part body 201 and the fixed magnet 103 on the insulating base 101 generate magnetic attraction, automatically adsorbing the copying part and preventing it from accidentally slipping out due to gravity or vibration.
[0088] Magnetic attraction provides contactless fixation, eliminating the need for additional locking operations, while also allowing for quick one-handed disassembly.
[0089] II. Establishment of Electrical Conduction Path
[0090] 1. The fixed metal plate 102 is connected to the metal plate slot 2013.
[0091] When the copying part is inserted into place, the fixing metal plate 102 on the fixture base 1 is inserted into the metal plate slot 2013 of the copying part.
[0092] The fixed metal plate 102 is directly electrically connected to the test motherboard, forming the main electrical path from the circuit board to the profiling part.
[0093] 2. Adaptive contact of movable metal spring 202
[0094] One end of the movable metal spring 202 on the conforming part extends into the battery mounting groove 2011 and contacts the electrode of the battery to be tested; the other end extends into the metal plate slot 2013 and fits tightly with the inserted fixed metal plate 102.
[0095] The elastic design of the spring can adapt to battery size tolerances and insertion deviations, ensuring stable electrode contact pressure and avoiding poor connection or excessive contact resistance.
[0096] III. Test Execution
[0097] After the battery under test is placed in the battery placement slot 2011, its position is precisely limited by the contour slot, and at the same time the movable metal spring 202 presses its electrodes together to form a reliable electrical contact.
[0098] The operator selects the test circuit by triggering switch 3, and the test motherboard applies the test signal through the path of fixed metal plate 102 → movable metal spring 202 → battery electrode.
[0099] IV. Disassembly and Replacement of Copying Parts
[0100] 1. Reverse sliding disassembly
[0101] After the test is completed, the operator overcomes the magnetic attraction (requiring a small external force) and slides the profile out in the opposite direction of the guide slot 2012.
[0102] The limiting insert 1012 disengages from the guide slot 2012, and the contour piece automatically separates from the fixed metal piece 102 and the movable metal spring 202, thus disconnecting the electrical circuit.
[0103] 2. Replace with new profile parts
[0104] Repeat the installation process, insert a new profile of another specification, and use magnetic fixing and guide limiting mechanisms to ensure that the new profile is quickly positioned and an electrical connection is established.
[0105] Optionally, the multi-purpose battery testing equipment also includes a display screen 4. The display screen 4 is electrically connected to the test motherboard and is used to display the test parameters and test results of the battery under test. The display screen 4 can visualize test parameters (such as voltage and internal resistance) and results (such as pass / abnormal) in real time, reducing reliance on external equipment; the intuitive data display facilitates quick decision-making, shortens the test cycle, and supports historical data backtracking, improving the intelligence level of the test process.
[0106] Optionally, the test fixture also includes a fixture cover 5. The fixture cover 5 is hinged to the fixture base 1 and is used to cover the detachable contour piece 2 in conjunction with the fixture base 1. The fixture cover 5 covers the test area to prevent external foreign objects from entering and causing electrical faults or battery short circuits, thereby improving safety.
[0107] In summary, the multi-purpose battery testing equipment provided in this embodiment has the following advantages:
[0108] ① Multi-specification compatibility: Modular profiled parts and test circuits can be switched with one click to adapt to multiple battery models, significantly reducing testing costs.
[0109] ② Electrical connection stability: The self-adaptive contact and magnetic guide limit design of the spring ensures stable and reliable transmission of test signals.
[0110] ③ Ease of operation: Horizontal sliding plug-in and magnetic fixation enable quick one-handed replacement, and trigger switch 3 simplifies the testing process.
[0111] ④ Enhanced safety: The insulating base 101 isolates the risk of electrical conduction, and the flip cover protects against the intrusion of foreign objects, ensuring a safe testing environment.
[0112] ⑤ Intelligent testing support: Integrated display screen 4 provides real-time data feedback, and preset programmed tests reduce human error.
[0113] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
