Description

Technical Field

[0001] The invention relates to the technical field of motor performance testing, in particular to a rapid tester for testing the performance of a wiper motor. Background Art

[0002] As a basic automotive component, the quality of the wiper motor determines the overall performance of the wiper, and also directly determines the safety and stability of the car during the wiping process. For example, the patent with publication number CN109507586A is a motor detection platform, which belongs to the field of motor detection and includes a detection platform, a first slider, a first detection motor, a coupling, an induction wheel, an electrical performance tester, a second slider, a second detection motor, an acceleration sensor, a turntable bearing, a vibration transmission member, a vibration sensor, a control box, a microprocessor, a relay, and a display screen. The electrical performance detection, acceleration performance detection, and vibration performance detection are integrated into one, which improves the efficiency of motor detection. Moreover, during the detection process, the motor changes position by sliding, and the motor is not carried or transferred, which reduces the detection error caused by transferring the motor and improves the accuracy of the detection; Another example is the patented power distribution cabinet power performance test technology field with publication number CN115327285A, which includes a power distribution cabinet inspection terminal, an inspection terminal connector, an inspection gear selector, a simulated load and a power performance detection display module. The power distribution cabinet inspection terminal is fixedly installed at the bottom of the distribution board of the power distribution cabinet body, and the power distribution cabinet inspection terminal includes a power line socket and a signal line socket. The power output power performance and signal output stability of the power distribution cabinet body can be quickly tested in a standardized manner, with high efficiency and high detection accuracy. The failure rate of the power distribution cabinet that can pass this factory inspection is greatly reduced, and it has good adaptability to different equipment. In the subsequent after-sales maintenance process, this system can also be used to quickly determine the fault; For example, a motor detection tooling disclosed in the patent with publication number CN118150875B relates to the technical field related to motor detection. The motor detection tooling comprises a horizontal frame, a movable platform and a second spring rod. A vertical frame is installed at one end of the top of the horizontal frame, and a first screw rod is installed at the other end of the top of the horizontal frame. By starting the first motor and driving the first screw rod to rotate, the movable platform can be driven to approach or move away from the vertical frame, thereby driving the fixed motor to move away from or approach the movable clamp, further improving the convenience during disassembly and assembly. At the same time, the movable clamp and the output shaft of the motor are flexibly connected. When the output shaft of the motor swings too much, the output shaft of the motor can be driven to quickly disengage from the movable clamp by moving the movable platform in the opposite direction, thereby improving the safety during use. Most of the above-mentioned existing technologies have improved their overall structure, while the existing rapid testers for wiper motor performance inspection mostly require users to manually and tediously connect the motor to be tested with the testing equipment during operation, which leads to cumbersome operation and troublesome disassembly, and cannot realize comparative testing, thus having certain usage limitations.
