Description
Technical Field
[0001] The present invention relates to the technical field of motor detection, and in particular to a detection device for a wiper motor. Background Art
[0002] A car's windshield wiper system is an important guarantee for driving safety. Its core function is to ensure a clear view for the driver by quickly clearing away rain, snow, mud and other impurities from the windshield. Especially in bad weather, wipers can effectively reduce visual interference caused by light refraction or water film coverage, helping the driver to accurately judge road conditions, identify traffic signs and pedestrian movements. At the same time, wipers can also keep the surface clean when dust flies or insects hit the glass, preventing long-term accumulation of stains and damage to the glass. Some models are equipped with smart sensor wipers that can automatically adjust the frequency according to the amount of rain, further reducing the risk of distraction during manual operation. Testing of wiper motors can ensure their reliability and safety in all weather conditions. By verifying key motor performance such as voltage, current, torque, and speed, it can prevent wiper failure due to motor malfunction, ensure drivers have clear vision in rainy and snowy weather, and reduce the risk of traffic accidents. At the same time, testing can identify potential problems (such as brush wear and insulation aging), extend the service life of the motor, reduce maintenance costs, and ensure that the product meets the quality and safety standards of the automotive industry, thereby improving the stability of the entire vehicle system and user trust.
[0003] Testing by varying motor loads comprehensively evaluates a motor's dynamic performance under different operating conditions, such as verifying its starting torque, overload capacity, and stability. This helps identify design flaws and ensures reliable operation under extreme loads. Simulating actual usage scenarios also optimizes the motor's energy efficiency and durability, preventing failures caused by sudden load changes. This improves product safety and service life, ensures compliance with industry standards, and reduces after-sales repair costs and safety risks.
[0004] A Chinese invention patent with announcement number CN111413615B discloses a tool for testing the performance of wiper motors. This device can quickly remove the wiper motor from the tool through the motor output shaft positioning seat and connector, enabling rapid replacement of the motor, improving testing efficiency, and eliminating the phenomenon of torque consumption. However, this device cannot change the load of the motor and cannot accurately detect the motor performance. At the same time, when the motor fails during the testing process, this device cannot quickly recycle the motor, reducing the motor testing efficiency and increasing the risk.

[0033] Working principle: When working, the motor 202 is placed on the placement plate 201. In the initial state, the push plate 2 309 limits the flip plate 1 208, and the limit block 1 206 limits the limit plate 212. The clamping plate 1 203 and the clamping plate 2 205 are driven to approach each other to clamp the motor 202. The motor 202 is placed, and the adjustment frame 102 is driven to slide on the processing box 101. The adjusting frame 2 104 drives the detection component 3 to move and adjust the position of the detection component 3. When the mounting frame 301 and the detection head 311 are aligned with a group of motors 202 that need to be detected, the adjusting frame 2 104 is driven to slide on the adjusting frame 1 102. The adjusting frame 2 104 drives the mounting frame 301 to approach the motor 202.

The driving power interface 302 is slid on the mounting frame 301. The power interface 302 is inserted into the power socket 204, and the power interface 302 is started. The power interface 302 supplies power to the motor 202 and detects the motor 202 at the same time. 2. Whether the current and voltage in the motor 202 are standard, during the detection process, the load of the motor 202 is changed by controlling the magnetic powder brake, and the changes in the current and voltage of the motor 202 are observed synchronously to determine whether the motor 202 meets the standard. During the detection process of the motor 202, two sets of noise detection heads 105 are driven close to the motor 202. The noise detection heads 105 detect the noise generated when the motor 202 is working. At the same time, two sets of spray racks 103 are driven to slide on the processing box 101. After the spray racks 103 are aligned with the motor 202, the spray racks 103 are driven to work and spray water to the motor 202 to restore the real working environment of the motor 202.
[0034] When the detection head 311 is connected to the output shaft of the motor 202, the push plate 2 309 is fitted with the clamping plate 205, the push plate 1 308 is fitted with the clamping plate 1 203, the top column 304 is aligned with the limit block 209, and the pressing plate 305 is fitted with the limit column 207. When the motor 202 fails or overheats during the detection process, the power interface 302 is driven to move on the mounting bracket 301, the power interface 302 falls off from the power socket 204, and the power supply to the motor 202 is released. At the same time, the adjustment block 1 306 and the adjustment block 2 307 are driven to descend on the mounting bracket 301, the adjustment block 1 306 presses the detection component 30, and the adjustment block 2 307 presses the push plate 1 308, and the push plate 1 308 and the push plate 2 309 move away from each other. The push plate 2 309 and the push plate 1 308 respectively drive the clamping plate 2 205 and the clamping The holding plates 1 203 move away from each other, the clamping plates 1 203 and the clamping plates 205 release the clamping of the motor 202, and at the same time drive the top column 304 to slide in the support frame 303, the top column 304 presses the limit block 209, the limit block 209 slides in the placement plate 201, the limit block 209 releases the limit on the flip plate 1 208, the top column 304 drives the pressing plate 305 to move, the pressing plate 305 presses the limit column 207, the limit column 207 drives the limit block 1 206 to slide on the placement plate 201, the limit block 1 206 releases the fixation of the limit plate 212, the flip plate 1 208 and the flip plate 2 211 are both reset by the torsion spring, the connecting column 213 slides in the flip plate 211, and at this time the flip plate 1 208 releases the support for the bottom of the motor 202, and the motor 202 falls into the recycling box of the processing component 1 by gravity.
[0035] While the adjusting block 2 307 presses the push plate 1 308, the adjusting block 2 307 drives the pressing column 315 to move, and the pressing column 315 presses the limit block 316. The limit block 316 drives the limit ring 313 to rotate on the mounting frame 301. The limit ring 313 releases the limit on the pushing column 312. The pushing column 312 impacts the motor 202 through the deformation recovery force of the spring 314, thereby increasing the falling speed of the motor 202 and improving the processing efficiency of the motor 202.
[0036] When the motor 202 falls into the recycling box of the processing component 1, the two sets of clamping plates 107 are driven to approach each other. The clamping plates 107 clamp the motor 202 and push the motor 202 to the middle section of the recycling box to align with the cooling head 108, drive the cooling head 108, and the cooling head 108 cools the motor 202.
