Description

Technical Field

[0001] This utility model relates to the field of charging fault detection technology, and in particular to a charging system fault detection device. Background Technology

[0002] With the rapid development of new energy vehicles, charging system fault detection devices have become core tools for ensuring charging safety and equipment stability. Traditional charging detection devices typically use a fixed plug-in interface structure, with a single plug specification that cannot adapt to the diverse plug standards (such as national standards, European standards, American standards, etc.) of different vehicle models or charging piles, resulting in poor compatibility of the detection equipment. Furthermore, the plug is rigidly connected to the detection circuit, and long-term plugging and unplugging can easily cause interface wear and poor contact, requiring the replacement of the entire detection module, which results in high maintenance costs. Therefore, it is necessary to improve the above-mentioned problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example: See Figure 1-4 This utility model discloses a charging system fault detection device, comprising a housing 1, a control panel 2 on the inner top surface of the housing 1, a fixing plate 3 on one upper side of the control panel 2, and a mounting plate 4 on the top surface of the fixing plate 3. Multiple fixing bolts pass through the mounting plate 4 and the fixing plate 3. The nuts of the fixing bolts have anti-slip textures and are round knob-shaped. A connecting ring 5 is located in the center of the top surface of the mounting plate 4. A cover plate is hinged to one side of the connecting ring 5, and a snap-fit ​​protrusion is hinged to the other side of the connecting ring 5. The cover plate has corresponding slots for the snap-fit ​​protrusions. The bolt connection structure between the mounting plate 4 and the fixing plate 3 facilitates quick disassembly and maintenance. The anti-slip textured round knob-shaped nuts increase the friction of manual turning, preventing slippage during operation. The connecting ring 5 and the snap-fit ​​protrusion cooperate to lock the cover plate in place, preventing detection. In case of accidental contact or contamination of the interface during the process, two C-shaped frames 6 are symmetrically arranged on the outer walls of both sides of the plug ring 5. The bottom ends of the two C-shaped frames 6 pass through the inner wall of the plug ring 5, and a first arc-shaped block is fixed to the bottom end of the C-shaped frame 6. The symmetrically arranged C-shaped frames 6 make elastic contact with the plug gun interface through the first arc-shaped block, which can accommodate plugs of different sizes, improve interface compatibility and clamping stability. A first arc-shaped plate is fixed to the upper end of the C-shaped frame 6. A spring is sleeved on the C-shaped frame 6 at the inner wall of the plug ring 5. One end of the spring abuts against one side of the first arc-shaped block. A hinge seat is provided on the outer wall of the plug ring 5. The pivot of the hinge seat passes through the lower middle part of the C-shaped frame 6. The spring provides buffer pressure to reduce the wear of the interface caused by the insertion and removal impact. The hinge seat and the pivot allow the C-shaped frame 6 to be finely adjusted in angle, further adapting to non-standard plugs and extending the service life of the interface.

[0019] In this invention, a gun connector 7 is fixedly connected to the mounting plate 4 inside the plug ring 5. A male connector 8 is provided at the bottom of the gun connector 7, and a female connector 9 is plugged into the male connector 8. The modular design of the male connector 8 and the female connector 9 facilitates the replacement of gun connectors 7 with different standards, solves the problem of single interface specifications in traditional testing devices, and reduces upgrade costs. A cable 10 is connected to the female connector 9. A storage box is provided at the lower end of the housing 1 below the gun connector 7. A cable reel 11 is provided at one end of the storage box. The cable reel 11 realizes automatic winding and unwinding of the cable 10, avoiding cable bending damage caused by manual winding and improving the efficiency of testing operations. A limiting frame 12 is provided at the upper end of the storage box above the cable reel 11. The cable 10 passes through the limiting frame 12 and rotates to be stored on the cable reel 11. The limiting frame 12 restricts the winding and unwinding path of the cable 10, preventing the cable 10 from shifting or stacking and jamming during winding, ensuring smooth storage and reducing wear on the cable sheath.

[0020] Working principle: When using this utility model, firstly, select the appropriate plug-in interface 7 according to the plug standard (such as national standard / European standard) of the charging pile to be tested, insert the male connector 8 at its bottom into the female connector 9 on the mounting plate 4 and lock it, close the cover plate of the plug ring 5 and fix it with the buckle protrusion, then pull out the cable 10 from the cable reel 11, pass it through the limiting frame 12, and connect it to the charging pile detection port, power on and start the control panel 2 to complete the self-test; during the test, insert the plug-in interface 7 into the charging pile socket, the first arc within the C-shaped frame 6 The block retracts under pressure, and the spring buffers the impact of insertion and removal, ensuring tight contact at the interface. The control panel 2 sends simulated charging commands through cable 10 and collects voltage, current, and communication protocol parameters in real time, dynamically analyzes the data, and triggers an abnormal alarm. After the test is completed, the plug-in interface 7 is unplugged, the spring resets and releases the plug, the cable reel 11 automatically retracts the cable 10, and the limit frame 12 constrains the path to prevent bending. If it is necessary to switch standards, the cover can be opened to replace the plug-in interface 7. Finally, the power is turned off and the cable is stored, completing the entire process test. The device is now in use.
