Description

Technical Field

[0001] This utility model relates to the field of electric bicycle circuit resistance measurement technology, and in particular to an alarm device for measuring electric bicycle circuit resistance. Background Technology

[0002] In the operation of modern electric bicycles, accurate measurement of line resistance is crucial to ensuring the safety, stability and high efficiency of the vehicle. With the continuous development of electric bicycle technology, its circuit system is becoming increasingly complex, containing a large number of cable connections and various functional circuit boards. Changes in line resistance may not only affect the power output of the electric bicycle, but may also cause a series of safety hazards such as over-discharge of the battery and overheating of the motor.

[0003] The distribution of circuit testing points in existing electric bicycles is inconsistent. Some testing points are located on the cables, while others are located on the circuit boards. This situation makes it difficult to connect the testing points to the electrical contacts during the testing process. When the testing point is on the cable, the structural characteristics of the cable, such as the insulation sheath and the cable's flexibility, make it difficult to fix the testing contact. It often requires extra effort to peel off the insulation layer and ensure a stable connection of the testing contact. Slight carelessness may damage the cable and affect its subsequent use. For testing points located on the circuit board, the limited space and compact component layout of the circuit board, along with the possible obstruction from other components around the testing point, make it difficult for the testing probe to make accurate and stable contact with the testing point. Poor contact is likely to occur, which seriously affects the accuracy and reliability of resistance measurement and greatly hinders the effective detection of the resistance of electric bicycle circuits. Utility Model Content

[0004] In order to overcome the problem that existing electric bicycle circuit resistance measuring devices have inconvenient electrical contact connection for testing, as the circuit detection points are sometimes on the cable and sometimes on the circuit board, this utility model provides an electric bicycle circuit resistance measuring alarm device.

[0005] The technical solution is as follows: an electric bicycle circuit resistance measurement alarm device, including a loop resistance detection component and a circuit probe component; the circuit probe component is externally mounted on the loop resistance detection component; the loop resistance detection component includes a detector, a terminal block, a monitoring screen, a control panel, and an alarm light; the circuit probe component includes a circuit test pen, alligator clips, test leads, and terminals.

[0006] Furthermore, a wiring board is provided on the upper surface of the detector, and the wiring holes inside the wiring board are electrically connected to the detector; a monitoring screen is provided on the front surface of the detector; and a control panel is provided below the monitoring screen.

[0007] Furthermore, alarm lights are installed on both sides of the front end of the detector, and the detector controls the alarm light switch.

[0008] Furthermore, the upper end of the terminal block is provided with terminals, which are inserted into the holes inside the terminal block and electrically connected.

[0009] Furthermore, one end of the terminal block is provided with a test lead wire, and the test lead wire is electrically connected to the terminal block; the other end of the test lead wire is provided with a circuit test pen, and the circuit test pen is electrically connected to the test lead wire.

[0010] Furthermore, one end of the circuit test pen is equipped with a test alligator clip, and the circuit test pen is inserted into the test alligator clip with an interference fit.

[0011] Furthermore, an electrical connection is established between the electrical probe at one end of the circuit test pen and the electrode inside the hole of the alligator clip.

[0012] The beneficial effects are as follows: This utility model achieves the combined function of clamping electrical connection and contact connection of cables in the circuit by splicing and combining the circuit detection pen and the test alligator clip in the circuit probe assembly. This satisfies the measurement needs of two circuit detection methods: circuit clamping measurement and probe contact measurement, and improves the convenience of measurement. The electrical signals detected by the circuit detection pen and the test alligator clip are transmitted to the detector for signal processing and analysis through the test leads, terminals and terminal blocks. The real-time detection data is then displayed on the monitoring screen, which greatly improves the intuitiveness of the detection results.

[0013] By setting up alarm lights, the alarm function of abnormal circuit resistance is realized through the illumination of alarm lights, which greatly improves the prompting efficiency of fault circuit detection points. Attached Figure Description

[0023] The upper surface of the detector 101 is provided with a wiring board 102, and the wiring holes inside the wiring board 102 are electrically connected to the detector 101; the front surface of the detector 101 is provided with a monitoring screen 103; and the lower part of the monitoring screen 103 is provided with a control panel 104.

[0024] Alarm lights 105 are provided on both sides of the front end of the detector 101, and the detector 101 controls the switch of the alarm lights 105.

[0025] The upper end of the terminal block 102 is provided with a terminal post 204, which is inserted into the hole inside the terminal block 102 and electrically connected.

[0026] By setting the alarm light 105, the alarm function of abnormal circuit resistance is realized by illuminating the alarm light of the alarm light 105, which greatly improves the prompting efficiency of fault circuit detection points.
